Can somebody help me please... Thank you so much

Answer 1

QUESTION C


`({9}^(4) ) ^{ (1)/(4) } = {9}^(1)`


Reason: The law of exponents says that,


`( {a}^(m) ) ^(n) = {a}^(mn)`

This implies that,



`({9}^(4) ) ^{ (1)/(4) } = {9}^{4 * (1)/(4) } = {9}^(1)`


QUESTION D
The given exponential expression is


`({5}^{ (1)/(3) } ) ^( 3 ) = {5}^(1)`
Reason:

The law of exponents says that,


`( {a}^(m) ) ^(n) = {a}^(mn)`
Thus, when an index number is raised to another index or exponent, the exponent will multiply.

This implies that,




`({5}^{ (1)/(3) } ) ^( 3 ) = {5}^{ (1)/(3) * 3} = {5}^(1)`
