Question

2- Calcule o valor das expressões:
a) √18-√100- √64
b) √1+√4+√9+√16+√49+√64

eu quero calculos pfvr!!!

Answer 1

$\mathsf{\sqrt{18}=\sqrt{9.2}=3\sqrt{2}}$

$\mathsf{\sqrt{100}=10}$

$\mathsf{\sqrt{64}=8}$

$\mathsf{\sqrt{18}-\sqrt{100}-\sqrt{64}=3\sqrt{2}-10+8=3\sqrt{2}-2}$

b)$\mathsf{\sqrt{1}+\sqrt{4}+\sqrt{9}+\sqrt{16}+\sqrt{49}+\sqrt{64}}\\\mathsf{1+2+3+4+7+8=25}$
