Answer 1

Answer:

$a = \frac { \sqrt { 5 } } { 1 5 } ,\:a = -\frac {\sqrt{5}}{15}$

Step-by-step explanation:

We are given the following expression which are to solve for a and give the answer in radical form:

$\frac{2}{3a^2} =30$

To solve this, we will multiply both the sides by $3a^2$ to get:

$\frac{2}{3a^2}\cdot \:3a^2=30\cdot \:3a^2$

Simplify it to get:

$2=90a^2$

$a = \frac { \sqrt { 5 } } { 1 5 } ,\:a = -\frac {\sqrt{5}}{15}$
