Question 281650
Basically, they want you to write {{{8a^3}}} in the form of {{{x^3}}} where 'x' is some expression. Since we can write 8 as {{{2^3}}}, this means that {{{8a^3=2^3a^3}}}



Now use the property {{{a^x*b^x=(ab)^x}}} to rewrite {{{2^3a^3}}} into {{{(2a)^3}}}. So {{{2^3a^3=(2a)^3}}} which means that {{{8a^3=(2a)^3}}}
