a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$\sqrt{50}-\sqrt{128+}; \sqrt{32}$$

Answer

5*sqrt(2)-8*sqrt(2)+;4*sqrt(2)

Solution


Simplify  \(\sqrt{50}\)  to  \(5\sqrt{2}\).
\[\begin{aligned}&5\sqrt{2}-\sqrt{128}+\\&\sqrt{32}\end{aligned}\]
Simplify  \(\sqrt{128}\)  to  \(8\sqrt{2}\).
\[\begin{aligned}&5\sqrt{2}-8\sqrt{2}+\\&\sqrt{32}\end{aligned}\]
Simplify  \(\sqrt{32}\)  to  \(4\sqrt{2}\).
\[\begin{aligned}&5\sqrt{2}-8\sqrt{2}+\\&4\sqrt{2}\end{aligned}\]
