Question

7 mũ 2 - 36 : 3 mũ 2 
10 mũ 4 : {12-[(3 mũ 3 +1 ) :14 ]}

Answer 1

\(a,=49-36:9=49-4=45\\ b,=10^4:\left(12-28:14\right)=10^4:\left(12-2\right)=10^4:10=10^3=1000\)

Answer 2

\(7^2-36:3^2=49-36:9=49-4=45\\ 10^4:\left\{12-\left[\left(3^3+1\right):14\right]\right\}=10^4:\left\{12-2\right\}=10^4:6=16500\)
