Question

calcular a radiciação

Answer 1

h) 3√13²-5²
3√169-25
3√144 ⇒ √144 = 12
3.12
36

i) 3√13²-3√5²
3√169 - 3√25 ⇒ √169 = 13 e √25 = 5
3.13 - 3.5 
39-15
24

Answer 2

$h)3 \sqrt{13^{2} - 5^{2} } = \\ \\ 3 \sqrt{(13 - 5) .(13 + 5)} = \\ \\ 3 \sqrt{8.18} = \\ \\ 3 \sqrt{144} = \\ \\ 3 \times 12 = 36\\ \\ i)$
$3 \sqrt{13^{2} } - 3\sqrt{5 ^{2} } = \\ \\ 3 \times 13 - 3 \times 5 = \\ \\ 39 - 15 = \\ \\ 24$
