Select the expressions that are equivalent to (picture)

Answer 1

Hey there :)

$\frac{5}{6x^4}$

When you take x⁴ from the denominator to the numerator, you get x⁻⁴
Therefore, first option: $\frac{5x^-^4}{6}$ is one correct expression

When you exchange the numerator and denominator, you will have negative powers on them. Such as when you take 6 to the numerator you will have 6⁻¹ and 5 to the denominator is 5⁻¹
So, second option : $\frac{6^-^1x^-^4}{5^-^1}$ is another right expression.
