Question

Convert the scientific notation to a decimal number. Type the correct answer in the box. 4 × 10-5 cm = cm

Answer 1

`4 * 10^(-5)cm = 0.00004cm`

Step-by-step explanation:

Given

`4 * 10^(-5)cm = [\ ]cm`

Required

Solve

Apply law of indices

`4 * (1)/(10^5)cm = [\ ]cm`

Evaluate 10^5

`4 * (1)/(100000)cm = [\ ]cm`

`4 * 0.00001cm = [\ ]cm`

`0.00004cm = [\ ]cm`

Hence:

`4 * 10^(-5)cm = 0.00004cm`
