Question

The speed of lights is about 10 -18 write this number using a positive exponent

Answer 1

Given:

Speed of light =
`10^(-18)`

To find:

The number using a positive exponent.

Solution:

We have,

Speed of light =
`10^(-18)`

Using properties of exponents, it can be written as

Speed of light =
`(1)/(10^(18))`
`[\because a^(-n)=(1)/(a^n)]`

Therefore, using a positive exponent the speed of light is about
`(1)/(10^(18))`.
