Question

1)calcule:

a)√49+√16=

b)³√8 ‐⁴√16=

c)‐5√9+2√169=

d)10³√2+4³√2‐³√2 =

e)√18+2√50=​

Answer 1

Explicação passo-a-passo:

$a) \sqrt{49} + \sqrt{16} = 7 + 4 = 11$

$b) \sqrt[3]{8} - \sqrt[4]{16} = 2 - 2 = 0$

$c) - 5 \sqrt{9} + 2 \sqrt{169} = - 5.3 + 2.13 = - 15 + 26 = 11$

$10 {}^{3} \sqrt{2} + 4 {}^{3} \sqrt{2} - \sqrt[3]{2} = 1000 \sqrt{2} + 64 \sqrt{2} - \sqrt[3]{2} = 1.064 \sqrt{2} - \sqrt[3]{2}$

$e) \sqrt{18} + 2 \sqrt{50} = \sqrt{3 {}^{2} .2} + 2 \sqrt{2.5 {}^{2} } = 3 \sqrt{2} + 50 \sqrt{2} = 52 \sqrt{2}$
