Solution:

Given:


a = (3)/(4)

Square both sides of the given equation:


a = (3)/(4)


\rightarrow (a)^(2) = \text{\huge{[}}(3)/(4)\text{\huge{]}}^(2)

Simplify the equation:


\rightarrow a^(2) = \text{\huge{[}}(3)/(4)\text{\huge{]}}\text{\huge{[}}(3)/(4)\text{\huge{]}}


\rightarrow a^(2) = \text{\huge{[}}(3^(2) )/(4^(2) )\text{\huge{]}}


\rightarrow \boxed{a^(2) =(9 )/(16 )}

Explanation:

Given:-


a = (3)/(4)

Therefore,


{a}^(2) = ( { (3)/(4) })^(2) \\ \: \: = \frac{ {3}^(2) }{ {4}^(2) } \\ = (9)/(16)
