Question

Algebra help please?

Answer 1

so now for this first one

you have

\[\frac{ \sqrt{18} }{ 3\sqrt{36} }\]

You know √18 is just √9*√2
and you know √9 is 3.....so the top is 3√2

you also know √36 is just √9*√4
and you know √9 =3 and √4 = 2

so the bottom leaves 3(3)(2) = 18

so you have

3√2
------
18

simplified gives

√2
