Question

Efetue a expressão matemática .
X=[18+½.(3,2+8,8)–25+¼]²

Answer 1

Explicação passo a passo:

Vamos lá!

$\large X = [18+\frac{1}{2}\cdot (3,2 + 8,8) - 25 + \frac{1}{4}]^2 \\\large X = [18+\frac{1}{2}\cdot (\frac{32}{10} + \frac{88}{10}) - 25 + \frac{1}{4}]^2 \\\large X = [18+\frac{1}{2}\cdot (\frac{120}{10}) - 25 + \frac{1}{4}]^2 \\\large X = [18+\frac{1}{2}\cdot 12 - 25 + \frac{1}{4}]^2 \\\large X = [18+6 - 25 + \frac{1}{4}]^2 \\\large X = [-1 + \frac{1}{4}]^2 \\\large X = [-\frac{3}{4}]^2 \\\large X = \frac{9}{16}$

Bons estudos!
