Question

What is the standard form of 0.00000015

Answer 1

Answer:

(1.5)to the power of -7

Answer 2

$\sf 0.00000015 = 1.5 \times {10}^{ - 7}$

Given :

The number 0.00000015

To find :

The standard form of the number

Concept :

The standard form of any given number is

$\sf = m\times {10}^{n}$

Where m is a number such that 1 ≤ m < 10 and n is the exponent of 10

Solution :

Step 1 of 2 :

Write down the given number

The given number is 0.00000015

Step 2 of 2 :

Write down the standard form

$\sf 0.00000015$

$\sf = 15 \times 0.00000001$

$\sf = 15 \times {10}^{ - 8}$

$\sf = 1. 5 \times {10}^{ 1} \times {10}^{ - 8}$

$\sf = 1. 5 \times {10}^{ - 7}$
