Question

Podem me ajudar para amanhã

Answer 1

$\sqrt{50 \times 100 } + \sqrt{5 \times 100} = 10 \sqrt{50 } + 10 \sqrt{5} = 10 \sqrt{25 \times 2} + 10 \sqrt{5} = (10 \times 5) \sqrt{2} + 10 \sqrt{5} = 50 \sqrt{2} + 10 \sqrt{5}$

Answer 2

24)

$( \frac{1}{2^{1} } + \frac{1}{2 ^{2} }) ^{-2}$

$( \frac{1}{2} + \frac{1}{4} }) ^{-2}$

$( \frac{2+1}{4})^{-2}$

$( \frac{3}{4})^{-2}$

$\frac{1}{(\frac{3}{4})^{2} }$

$\frac{1}{\frac{9}{16}}$

$\frac{1}{1} . \frac{16}{9}$

$\frac{16}{9}$
