Question

Evaluate the expression for x = 3 and y= 4.

Answer 1

• x=3
• y=4

`\\ \large\sf\longmapsto -(4x^3)/(3y^2)`

`\\ \large\sf\longmapsto -(4(3)^3)/(3(4)^2)`

`\\ \large\sf\longmapsto -(4(27))/(3(16))`

`\\ \large\sf\longmapsto -(108)/(48)`

`\\ \large\sf\longmapsto -(9)/(4)`

Answer 2

Answer:

O C) - 9/4

Explanation:

- 4x^3/3y^2 where x = 3 and y = 4

Substitute x for 3 and y for 4

- 4(3)^3/3(4)^2

Simplify the exponents

- 4(27)/3(16)

Multiply

- 108/48

Simplify

- 9/4
