Question

(5.391 ´ 10-7) + (2.5531 ´ 10-6) =

Answer 1

`(5.391 * 10^(-7)) + (2.5531 * 10^(-6)) = 3.0922 * 10^(-6)`

Step-by-step explanation:

Given

`(5.391 * 10^(-7)) + (2.5531 * 10^(-6))`

Required

Solve

`(5.391 * 10^(-7)) + (2.5531 * 10^(-6))`

Remove the brackets

`5.391 * 10^(-7) + 2.5531 * 10^(-6)`

Express
`10^(-7)` as
`10^(-1-6)`

`5.391 * 10^(-1-6) + 2.5531 * 10^(-6)`

Apply law of indices

`5.391 * 10^(-1) * 10^(-6) + 2.5531 * 10^(-6)`

`0.5391 * 10^(-6) + 2.5531 * 10^(-6)`

Factorize:

`(0.5391 + 2.5531)10^(-6)`

`(3.0922)10^(-6)`

Remove bracket

`3.0922 * 10^(-6)`

Hence:

`(5.391 * 10^(-7)) + (2.5531 * 10^(-6)) = 3.0922 * 10^(-6)`
