$\sqrt{70}$ $sqrt(70)$ is already in simplest form

The prime factorisation of $70$ $70$ is:

$70 = 2 \cdot 5 \cdot 7$ $70 = 2 * 5 * 7$

Since there are no square factors, $\sqrt{70}$ $sqrt(70)$ does not simplify.

In general, if you find a square factor $a^{2}$ $a^2$ where $a > 0$ $a > 0$ , then:

$\sqrt{a^{2} b} = \sqrt{a^{2}} \sqrt{b} = a \sqrt{b}$ $sqrt(a^2 b) = sqrt(a^2) sqrt(b) = a sqrt(b)$
