Question

Evaluate for x=2 and y=3: x^2y^-3/x^-1y

Answer 1

8/81

Explanation:

It's most efficient to simplify the quotient algebraically before inserting the values of the variables x and y.

The given expression reduces to x³ / y^4.

Substituting 2 for x and 3 for y, we get:

(2)³ 8

--------- = ---------- (Agrees with first given possible answer)

(3)^4 81
