Answer:
[tex](mn)^3 = m^3 n^3[/tex]
Step-by-step explanation:
Given
[tex](mn)^3[/tex]
Required
Select an equivalent expression
To solve this question, we apply the following law of indices:
[tex](xy)^b = x^b * y^b[/tex]
Similarly:
[tex](mn)^3 = m^3 * n^3[/tex]
[tex](mn)^3 = m^3 n^3[/tex]
D. is correct
