Question

3a²-c³
The value of the expression is
(Simplify your answer.)
A=4 C=-2

Answer 1

56

Explanation:

The question is asking us to evaluate the expression
`\bf{3a^2-c^3}`, given that a = 4 and c = -2.

I plug in the values:

`\sf{3(4)^2-(-2)^3}`

`\sf{3(4)^2+2^3}`

`\sf{3*16+8}`

`\sf{48+8}`

`\boxed{\boxed{56}}`

Therefore, the answer is 56.

Answer 2

56

Explanation:

3a² - c³ ( substitute a = 4 , c = - 2 into the expression )

3(4)² - (- 2)³

= 3(16) - (- 8)

= 48 + 8 = 56
