Answer 2

Answer:

Given:-

• To solve 30 divided by 3 root 5

Solution :-

• ★ We know that to rationalise a denominator, the first step of this Question is also the same

$\bold{ \underline{ \red{rationalising \: the \: denominator}{} }{} }{}$

$\frac{30}{ \sqrt[3]{5 } } \\ \\ \bold{ \green{ \frac{30 \times \sqrt[3]{5} }{ \sqrt[3]{5 } \ \times \sqrt[3]{5} } }{ } }{} = \bold{ \green{ \frac{90 \sqrt[]{5} }{45} }{} }{} = 2 root 5$

• At the last step we take the conjugate of the denominator so, it became a rational number and thus solved
