Question

A^2 when a=3/4?? Thank you

Answer 1

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 )}`

Answer 2

Explanation:

Given:-

`a = (3)/(4)`

Therefore,

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