Question

Se A=2 e B=3, calcule o valor das expressões

Answer 1

$a) \frac{ {2}^{3} \times 3}{ {3}^{2} } = \frac{24}{9} = 2.6666..$

$b) {2}^{3} = 8$

$c) {2}^{3} \times {3}^{2} = 8 \times 9 = 72$

$d){(2 \times {3}^{2} ) }^{2} = (2 \times 9)^{2} = {18}^{2} = 324$

$e)(3 + 2)^{2} - {2}^{2} = {5}^{2} - 4 = 25 - 4 = 21$
