Question

2) Calcule:

a) √x²/49 =
b) √x²/25 =
c) √4/9x⁸ =
d) √49/64x¹⁰ =
e) √25/81yx⁶ =
f) √121/100 x²m⁸ =

Answer 1

Resposta:

A) $=\frac{x}{49}$

B) $=\frac{x}{25}$

C) $=\frac{2}{9x^8}$

D) $=\frac{9}{32x^{10}}$

E) $=\frac{5\sqrt{2}yx^6}{81}$

F) $=\frac{21}{100m^8x^2}$

Explicação passo a passo:

A) $\frac{\left(\sqrt{x}\right)^2}{49}$

$=\frac{x}{49}$

B) $\frac{\left(\sqrt{x}\right)^2}{25}$

$=\frac{x}{25}$

C) $\frac{\sqrt{4}}{9x^8}$

$=\frac{2}{9x^8}$

D) $\frac{\sqrt{4}\cdot \:9}{64x^{10}}$

$=\frac{2\cdot \:9}{64x^{10}}$

$=\frac{2\cdot \:9}{2\cdot \:32x^{10}}$

$=\frac{9}{32x^{10}}$

E)$\sqrt{2}\frac{5}{81}yx^6$

$=\frac{5\sqrt{2}yx^6}{81}$

F) $\frac{\sqrt{1}\cdot \:21}{100x^2m^8}$

$=\frac{1\cdot \:21}{100m^8x^2}$

$=\frac{21}{100m^8x^2}$
