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

Answer:
B and D
Step-by-step explanation:
Expression B = 1/[tex]x^{-1}[/tex] = 1/ (1/x) = x
Expression D = [tex]x^{1/3}[/tex] [tex]x^{1/3}[/tex] [tex]x^{1/3}[/tex]
= [tex]x^{1/3 + 1/3 + 1/3}[/tex]
= [tex]x^{1}[/tex]
= x
as shown above the both the value of B and D are equal to x and hence the expressions are equivalent
