Question

Which expression is equivalent to StartRoot 120 x EndRoot?.

Answer 1

Here for 120, the expression for the start root and end root is given  

$\sqrt{120} =2\sqrt{30}$

What will be the expression for start root and enroot of 120?

Here we need to find $\sqrt{120}$

By simplifying the given expression, we get:

$120=2\times2\times2\times3\times5$

$120=(2^{2} )\times3\times5$

by taking square roots on both sides we get

$\sqrt{120} =2\sqrt{30}$

Thus for 120, the expression for the start root and end root is given  $\sqrt{120} =2\sqrt{30}$
