Question

Which of the following expressions are equivalent? Please explain so I can understand.

Answer 1

B and D

Explanation:

Expression B = 1/
`x^(-1)` = 1/ (1/x) = x

Expression D =
`x^(1/3)`
`x^(1/3)`
`x^(1/3)`

=
`x^(1/3 + 1/3 + 1/3)`

=
`x^(1)`

= x

as shown above the both the value of B and D are equal to x and hence the expressions are equivalent
