Let's solve the expression step by step:

Expression:

$-3(-2)^3 - (-4)$

Step 1: Evaluate the exponentiation

$(-2)^3 = -8$ So the expression becomes: $-3(-8) - (-4)$

Step 2: Multiply

$-3 \times (-8) = 24$ Now the expression is: $24 - (-4)$

Step 3: Subtract a negative

Subtracting a negative number is the same as adding it: $24 - (-4) = 24 + 4 = 28$

Final Answer:

$28$
