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

a) 15

b) 270.

<h3>How to solve the given expressions?</h3>

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

Distance between (-3,1) (1,5)
Mamont248 [21]

Answer & Step-by-step explanation:

For this problem, we will use the distance formula.

d=\sqrt{(x2-x1)^2+(y2-y1)^2}

For our (x1, y1), we will use (-3, 1). For our (x2, y2), we will use (1, 5). Now let's plug in our numbers and solve the problem.

d=\sqrt{(1-(-3))^2+(5-1)^2}

d=\sqrt{4^2+4^2}

d=\sqrt{16 + 16}

d=\sqrt{32}

d=5.657

So, the distance between (-3,1) and (1,5) is 5.657 units.
