Question

Please help!!!!1.
`{2}^(2) * (7 + 1)`2.
`{8}^(2) * 2 - 17`

Answer 1

Given the expression :

`2^2*(7+1)`

Make the sum operation first then the product operation

So, The result will be as following :

`\begin{gathered} 2^2=4 \\ 7+1=8 \\ \\ 2^2*(7+1)=4*8=32_{} \end{gathered}`

======================================================================

Given : the following expression :

`8^2*2-17`

In this expression , we need to do the product operation first then the subtract operation

So,

`\begin{gathered} 8^2*2-17 \\ =64*2-17 \\ =128-17 \\ =111 \end{gathered}`
