Question

(Raiz quadrada de 400-2×2+8) ÷ (raiz quadrada de 100-2 elevado a 3)

Answer 1

Resposta:

$\frac{\sqrt{2323} }{23}$

Explicação passo-a-passo:

$\sqrt{(400-2*2+8)/(100-2^{3} }$

$\sqrt{\frac{400-2*2+8}{100-2^{3} } }$

$\sqrt{\frac{400-4+8}{100-8} } \\\sqrt{\frac{404}{92} } \\\sqrt{\frac{101}{23} } \\\frac{\sqrt{101} }{\sqrt{23} }*\frac{\sqrt{23} }{\sqrt{23} }\\\frac{\sqrt{2323} }{23}$
