(b)
$3 \sqrt{243}$
(c)
$5 \sqrt{1024}$
(d)
$\sqrt{1024}$
(e)
$\sqrt{1244}$
quero cálculo

Answer 1

a) $\sqrt{625 \times \sqrt{144} }$
= $\sqrt{625 \times 12}$
= $\sqrt{625 \times 4 \times 3}$
= 2 x 25 $\sqrt 3}$
= 50 $\sqrt 3}$

(b) $3 \sqrt{243}$
= $3 \sqrt{81 \times 3}$
= 9 x 3 $\sqrt{3}$
= 27 $\sqrt{3}$

(c) $5 \sqrt{1024}$
= 5 x 32
= 160

(d) $\sqrt{1024}$
= $\sqrt{32 \times 32}$
= 32

(e) $\sqrt{1244}$
= 2 $\sqrt{311}$
