Question

If x= 3, y-12 and z=8, how do you evaluate: `y^2div(3z)+2x`?

Answer 1

`12`

Explanation:

To evaluate the expression, substitute the given values for x, y and z into it.

`y^2÷(3z)+2x" may be expressed as follows."`

`(y^2)/(3z)+2x`

and substituting in the given values.

`y^2/(3z)+2x=(-12)^2/(3xx8)+(2xx3)`

`=144/24+6rarr "divide before adding"`

`=6+6=12`
