Question

Resolva a expressão (2-1/2)²÷(2+1/2)²

Answer 1

Explicação passo-a-passo:

$(2 - \frac{1}{2} )^{2} \div ( 2 + \frac{1}{2} ) ^{2} = >$

$( \frac{3}{2} ) ^{2} \div ( \frac{5}{2} ) ^{2} = >$

$( \frac{3}{2} \div \frac{5}{2} ) ^{2} = >$

$( \frac{3}{2} \times \frac{2}{5} ) ^{2} = >$

$(3 \times \frac{1}{5} ) ^{2} = >$

$( \frac{3}{5} ) ^{2} = >$

$\frac{9}{25}$
