Question

Hi can anybody tell me the answerplease

Answer 1

Your answer would be 9216x

Explanation:

First you would want to simplify the first number and doing that would get you get 9

Second you would want to simplify the second number and get 1024

Third you would want to do 9 times 1024 and end up with 9216

At the very end add an X because that variable is still unknown

Answer 2

12
`x^(7)`

Explanation:

Using the rule of exponents

`a^(m)` ×
`a^(n)` ⇔
`a^((m+n))`

Given

3x² × 4
`x^(5)`

= 3 × x² × 4 ×
`x^(5)`

= 3 × 4 × x² ×
`x^(5)`

= 12 ×
`x^((2+5))`

= 12
`x^(7)`
