Question

sabendo que A=1/3+1/9 e B=27/4-1/2, então a √A•B é​

Answer 1

Resposta:

$\frac{3}{5}$

Explicação passo-a-passo:

MMC (3;9) = 9

$\frac{1}{3} + \frac{1}{9} = \\ \frac{3 + 1}{9} = \frac{4}{9}$

MMC (4; 2) = 4

$\frac{27}{4} - \frac{1}{2} = \\ \frac{27 - 2}{4} = \frac{25}{4}$

A =

$\frac{4}{9}$

B =

$\frac{25}{4}$

$\sqrt{a \times b} = \\ \sqrt{ \frac{4}{9} \times \frac{25}{4} } = \\ \sqrt{ \frac{25}{9} } = \frac{5}{3}$
