Question

Calcule o valor da expressao (2^2×2^-3×3^-1×3)^2

Answer 1

Resposta:

$\frac{1}{16}$

Explicação passo-a-passo:

$( {2}^{2} \times {2}^{ - 3} \times {3}^{ - 1} \times 3)^{2}$

${(4 \times ( \frac{1}{2})^{3} \times ( \frac{1}{3}) \times 3) }^{2}$

$(4 \times \frac{1}{8} \times \frac{1}{3} \times 3)^{2}$

$( \frac{4}{8} \times \frac{3}{3}) ^{2}$

$( \frac{1}{4} \times 1) ^{2}$

$( \frac{1}{4} ) ^{2}$

$\frac{1}{16}$
