Find the value of the expression below for r = 4 and t = 2
t^3 - r + 20 divided by r

The value of the expression is, 9

Step-by-step explanation:

Given: The expression

Substitute the value of r=4 and t=2 in above expression to find its value;

Cube: the cube of a number t is its third power, the result of the number multiplied by itself twice. i.e,

Now, solve further we have;

Further, divide the number 20 by 4 we get the result 5 ;

⇒ 8-4+5 = 4+5 =9

Therefore, the value of the expression is, 9.

51-50
