Question

√16 + √9 qual a resposta é urgente ?

Answer 1

Lembrete:

๏ $\sqrt[c]{a^b}=a^{\frac{b}{c}}$
--------------------------------------------------
$\sqrt{16}+\sqrt{9}=\\\sqrt{4\cdot 4}+\sqrt{3\cdot 3}=\\\sqrt{4^2}+\sqrt{3^2}=\\4^{\frac{2}{2}}+3^{\frac{2}{2}}=\\4^1+3^1=\\4+3=\\\boxed{\bold{7}}$
