Answer 1

C 2

Explanation:

We have the expression

`\left(m^(10)\right)\left(m^4\right)^(-2)`

Simplify
`\left(m^4\right)^(-2)`

`m^(4\left(-2\right))\\= m^(-8)`

So the expression becomes

`(m^(10))(m^(-8))` =
`m^(10) \cdot m^(-8)` by expanding the brackets

Apply rule for multiplying two exponents
`a^b\cdot \:a^c=a^(b+c)`

`m^(10) \cdot m^(-8) = m^(10 - 8) = m^2`

if
`m^x = m^2` then

`x = 2`
