I don't understand how or where to put these parenthesis. Please help me.

 

1. Insert paranthesis to make each statement true.

\(a. 2+3\times{4}^{2}+1=81\)

\(b. 2+3\times{4}^{2}+1=85\)

\(c. 2+3\times{4}^{2}+1=51\)

\(d. 2+3\times{4}^{2}+1=53\)

For a., insert parenthesis around 2 and 3. 

For b., insert parenthesis around 2 and 3 and another set around 42 and 1

For c., insert parenthesis around 3 and 4 2

For d., insert parenthesis around 4and 1.

For c, parentheses are unnecessary.
