## What is Earth age in scientific notation?

4.6 X 10^{9} years

For example the age of the Earth (see above) can be written as **4.6 X 10 ^{9} years**. This means that this number has 9 places after the decimal place – filled with zeros unless a number comes after the decimal when writing scientific notation. So 4.6 X 10

^{9}years represents 4600000000 years.

## What is Earth’s approximate size?

Both of these values are very close to the accepted modern values for the Earth’s circumference and radius, 40,070 km and 6378 km respectively, which have since been measured by orbiting spacecraft. The diameter of a circle is twice the radius, giving us a diameter for Earth of **12,756 km**.

## How big is the sun scientific notation?

Using scientific notation, the mass of the sun is **1.98892 * 1030 kilograms** and the mass of an electron is 9.10938 * 10-31 kilograms.

## What is the circumference of the Earth in scientific notation?

The Earth’s circumference is approximately **40,000,000 meters**. What is the radius of the earth in scientific notation? The relationship between circumference and radius is C=2πr.

## How do you write 150 in scientific notation?

Since 150 is such a small number to put into scientific notation, you simply **move the decimal place two to the left to create 1.5.** **Which when multiplied with 10 to the second power creates 150**.

## How do you write 400000 in scientific notation?

Why is 400,000 written as **4 x 105** in scientific notation?

## What is the scientific notation of 10000000?

10^{7}

10,000,000 (ten million) is the natural number following 9,999,999 and preceding 10,000,001. In scientific notation, it is written as **10 ^{7}**.

## What is the scientific notation for 1 million?

Words

Words | Decimal Representation | Scientific Notation |
---|---|---|

one million | 1,000,000 | 1 x 10^{6} |

ten million | 10,000,000 | 1 x 10^{7} |

one hundred million | 100,000,000 | 1 x 10^{8} |

one billion | 1,000,000,000 | 1 x 10^{9} |

## How is the number 3400000 written in scientific notation?

3,400,000 written in scientific notation is **3.4 × 10 ^{6}**. Simply place the decimal point to get a number between 1 and 10 and then count the digits to the right of the decimal to get the power of 10. 0.0000008 written in scientific notation is 8 × 10

^{–}

^{7}.

## When a very large number is written in scientific notation should the exponent be a positive or negative number?

positive

If you have a small number in decimal form (smaller than 1, in absolute value), then the power is negative for the scientific notation; if it’s a large number in decimal (bigger than 1, in absolute value), then **the exponent is positive** for the scientific notation.

## What is scientific form in math?

Scientific notation is **a way of writing very large or very small numbers**. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8. Created by Sal Khan and CK-12 Foundation.

## How do you write 38000 in scientific notation?

**The easiest way to do this is to do the following:**

- write down the original number: 38000.
- place the decimal point where we put it in 3.8 : 3.8000.
- count the number of places after the decimal point (or count the number of numbers after the decimal point): 3./8/0/0/0 ← there are 4 numbers after the decimal point.

## How do you write 2.0 in scientific notation?

If you wanted to express this sum in scientific notation, you’d write **2.0 x 10 ^{3}**. Here’s how we made that conversion. When you use scientific notation, what you’re really doing is taking a small number (i.e., 2.0) and multiplying it by a specific exponent of 10 (i.e., 10

^{3}).

## How do you write 27000 in scientific notation?

27,000 is written **27 × 10**.

## How do you write 0.004 in scientific notation?

**Scientific Notation**

- The power of 10 is positive when the number is larger than 1:4000=4×103 1 : 4000 = 4 × 10 3 .
- The power of 10 is negative when the number is between 0 and 1:0.004=4×10−3 1 : 0.004 = 4 × 10 − 3 .

## How do you write 0.000345 in scientific notation?

Convert from Real Number to Scientific Notation: 0.000345 = **3.45 × 10**.

The use of the [EE] key. For many calculators, including the TI –83 and TI 83 Plus, **the [EE] button is used to enter scientific notation**. The [EE] button can be found in yellow above the comma key [,].

## How do you convert standard notation to scientific notation?

To change a number from scientific notation to standard form, **move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive)**. You should move the point as many times as the exponent indicates.

## How do you write 500000 in scientific notation?

Answer: 500000 is converted as scientific notation **5×10 ^{5}**.
