Question

Answer 1

a,13,7.16,5-6,5.13,7

=13,7.(16,5-6,5)

=13,7.10

=137

b,\(2022+\left(\dfrac{1}{3}\right)^2.3^2\\ =2022+\left(\dfrac{1}{3}.3\right)^2\\ =2022+1^2\\ =2023\)

Answer 2

\(a,13,7.16,5-6,5.13,7=13,7.\left(16,5-6,5\right)=13,7.10=137\)

\(b,2022+\left(\dfrac{1}{3}\right)^2.3^2=2022+\left(\dfrac{1}{3}.3\right)^2=2022+11=2023\)
