Question

How would you do this question?

Answer 1

By using exponent properties, we will see that the solutions are:

a) 15

b) 270.

How to solve the given expressions?

Here you need to remember that:

$(\sqrt[n]{x} )^n = x$

a) First, we want to solve:

$(\sqrt{5})^2*(\sqrt{3} )^2$

And these are square roots, then:

Now if we apply the above relation, we get:

$(\sqrt{5})^2*(\sqrt{3} )^2 = 5*3 = 15$

b) Now we have the expression:

$(\sqrt[3]{9} )^3*(\sqrt{30})^2$

Again using the relation:

$(\sqrt[3]{9} )^3*(\sqrt{30})^2 = 9*30 = 270$
