Question

Gente me ajudem,por favor!​

Answer 1

Resposta:

a) $\sqrt{25}$ . $\sqrt{4}$ = 5 . 2 = 10

b) $\sqrt{x}$ . $\sqrt{16}$ = 3 . x = x

3² = 9 = $\sqrt{9}$

$\sqrt{16}$ = 4

Resposta:

$\sqrt{9}$ . $\sqrt{16}$ = 3 . 4 = 12

c) $\frac{\sqrt{100} }{\sqrt{25} } }$ = $\frac{10}{5}$ = 2

d) $\frac{\sqrt{1} }{\sqrt{4} }$ = $\frac{1}{2}$

e) $\sqrt{16}$ + $\sqrt{9}$ = 4 + 3 = 7

f) $\sqrt{100}$ - $\sqrt{36}$ = 10 - 6 = 4

g) $\sqrt{25}$ + $\sqrt{0}$ = 5 + 0 = 5

h) $\sqrt{16} - \sqrt{16}$ = 4 - 4 = 0

Espero ter ajudado! Bons estudos : )
