Question

How would you write this in scientific notation
0.2 x 10^6

Answer 1

The answer is 2 × 10⁵

Scientific notation is in a form: x × 10ⁿ, where x is a number from 1 to 9 and n is the number of decimal places.

0.2 = 2 / 10
1/xᵃ = x⁻ᵃ
2/10¹ = 2 × 10⁻¹

0.2 × 10⁶ = 2 × 10⁻¹ × 10⁶

xᵃ * xᵇ = xᵃ⁺ᵇ

0.2 × 10⁶ = 2 × 10⁻¹ × 10⁶ = 2 × 10⁻¹⁺⁶ = 2 × 10⁵
