Question

calcule:
h. (-5√10)²
i. (5√10)²
j. (10√5)²​

Answer 1

Resposta:

$h)( - 5 \sqrt{10}) {}^{2} = 250 \\ ( - 5 \sqrt{10}) {}^{2} \\ ( - 5) {}^{2} \times \sqrt{10} {}^{2} \\ 25 \times \sqrt{10} {}^{2} \\ ( - 5) {}^{2} \times \sqrt{10} {}^{2} \\ 25 \times 10 \\ ( - 5 \sqrt{10}) {}^{2} \\ 25 \times 10 \\ 250 \\ resposta \\ 250 \\ i)(5 \sqrt{10}) {}^{2} = 250 \\ (5 \sqrt{10}) {}^{2} \\ 5 {}^{2} \times \sqrt{10} {}^{2} \\ 25 \times \sqrt{10} {}^{2} \\ 5 {}^{2} \times \sqrt{10} {}^{2} \\ 25 \times 10 \\ (5 \sqrt{10}) {}^{2} \\ 25 \times 10 \\ 250 \\ resposta \\ 250 \\ j)(10 \sqrt{5}) {}^{2} = 500 \\ (10 \sqrt{5}) {}^{2} \\ 10 {}^{2} \times \sqrt{5} {}^{2} \\ 100 \times \sqrt{5} {}^{2} \\ 10 {}^{2} \times \sqrt{5} {}^{2} \\ 100 \times 5 \\ ( - 10 \sqrt{5}) {}^{2} \\ 100 \times 5 \\ 500 \\ resposta \\ 500$
