Question

How to express 0.000000085 in standard form

Answer 1

Answer:

The answer is 8.5×10^-8

Step-by-step explanation:

To express number in standard form we will write it as follow

a × 10^n where  1 ≤ a ≤ 10 and n is an integer

Mathematically

0.000000085 =$\frac{85}{1000000000}$

                        =   $\frac{85}{10^9}$

                        = 85 × 10^-8

                        = (8.5×10) × 10^-9

                        = 8.5 ×(10^1 × 10^-9)

                        =8.5 × (10^1+(-9) )        Using (a^m × a^n ) = a^m+n

                        =8.5 × 10^-8

Thus solved
