Scientific Notation

2.8E7 in Scientific Notation = 28000000 x 100

From the starting decimal point of 100000.0, shift 5 decimal places to the left, so the exponent for base 10 is 5. Therefore, the number in scientific notation is:

1.0 x 105

0167 in Scientific Notation = 0.167 x 103

3.92 × 10-4

It is: 4.0*10^-9

It is: 3.5*10^4 in scientific notation

It took me forever to learn scientific notation because of how the exponents seem backwards.

When you move the decimal to the left (towards the negative numbers in a line) your exponent will be positive. When you move the decimal to the right (towards the positive numbers in line) your exponent will be negative.

So since we need a number between 1-9 in order have scientific notation we have to move our decimal one place to the left.

10.4 -> 1.04 x 101

6.42 x 10 ^ -2

It is 2.646*10^2.

9,081,000 in Scientific Notation = 9.081 x 106

7.41711 x 105

213000000 in scientific notation is 2.13 x 10^8

It is 3.9999999*10-1

1.72 × 102 written in regular notation is 172

Here are the quick examples of the numbers written in scientific notation:

3.4 = 3.4 x 100

34.0 = 3.4 x 10

It is: 3.34*10^-4

It is 4.356*10^6 in scientific notation

6.02E3 or 6.02 x 103

The milli- prefix means "× 10^-3"

→ 22000 mg = 2.2 × 10^4 mg = (2.2 × 10^4) × 10^-3 g = 2.2 × (10^4 × 10^-3) g = 2.2 × 10^(4 + -3) g = 2.2 × 10^1 g

6180000 = 6.18*106

It is 0.

Exponential notation is a way of writing numbers that allows you to move the decimal point in a number. This is also referred to as standard form or scientific notation.

38,600 in scientific notation is 3.86 × 104

54.10000000 in scientific notation = 5.41 × 101

7.54 × 102
