Question

Express the following in exponential notation:
(-13) X (-13).
35 times

Answer 1

`(-13) * (-13) = (-13)^(2)`

`35 * 35 = 35^(2)`

Explanation:

Given

`(-13) * (-13)`

Required

Express as an exponential notation

`(-13) * (-13)`

Apply the following law of indices

`x^a * x^b = x^(a+b)`

This gives:

`(-13) * (-13) = (-13)^(1+1)`

`(-13) * (-13) = (-13)^(2)`

The second complete is incomplete; However, I'll assume it is: 35 times 35

`35 * 35`

Using the same law applied in (1) above:

`35 * 35 = 35^(1+1)`

`35 * 35 = 35^(2)`
