Find the value of each expression 30 =3x2

+3.16 or -3.16

Step-by-step explanation:

To solve this question we will have to follow the step by step procedure

30=3x2

Which means we will have to make x the subject of formula

So let's solve the question

Let's divide both sides by 3

x2=10

Let's square root both sides

X=+or-√10

We can actually solve further as

x=+3.16 or -3.16

the answer is 62.8 cubic units
