Question

please help!!!!1.${2}^{2} \times (7 + 1)$2.${8}^{2} \times 2 - 17$

Answer 1

Given the expression :

$2^2\times(7+1)$

Make the sum operation first then the product operation

So, The result will be as following :

$\begin{gathered} 2^2=4 \\ 7+1=8 \\ \\ 2^2\times(7+1)=4\times8=32_{} \end{gathered}$

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

Given : the following expression :

$8^2\times2-17$

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

So,

$\begin{gathered} 8^2\times2-17 \\ =64\times2-17 \\ =128-17 \\ =111 \end{gathered}$
