Question

what is the value of 10x^3 y^2 when x=-2 and y=-3

Answer 1

Answer:

-720

Step-by-step explanation:

We are given the expression:

$10x^3y^2$

and asked to evaluate when x= -2 and y= -3.

Therefore, we must substitute -2 for x and -3 for y.

$10(-2)^3*(-3)^2$

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Evaluate the first exponent.

⇒ (-2)³ = -2 * -2 * -2= 4*-2= -8

$10(-8)*(-3)^2$

Evaluate the second exponent.

⇒ (-3)²= -3 * -3= 9

$10(-8)*9$

Multiply 10 and -8.

$-80*9$

Multiply -80 and 9.

$-720$

The value of 10x³y² at x= -2 and y= -3 is -720
