Which is equivalent to 16 3/4x?

The answer

the question is not very clear,

its complement may be Which is equivalent to 16 ^ 3/4x?

-4√16^3x

-4√16^3

-3√16^4x

-3√16^4

perhaps the 16 3/4x should be written as [16 ^ 3] / 4x, or 16 ^ (3 / 4x)

or - [16 ^ (3 / 4) ] x

If the question is [16 ^ 3] / 4x, then none of the choices is equivalent to this

if the question is 16 ^ (3 / 4x), it is equivalent to 4x-th root of 16^3

so if the question is - [16 ^ (3 / 4) ] x

so - [16 ^ (3 / 4) ] x = ( - 4√16^3) x it is 4th root of 16^3 times x

so the choice is - 4√16^3x
