Apologies for any confusion. Let's go through the calculation again.

-4 (3 + 12^0) + 15^0

12^0 is equal to 1, since any number raised to the power of 0 is 1.

-4 (3 + 1) + 1

-4 (4) + 1

-16 + 1

-15

So, the answer is -15.

To solve this expression step-by-step, we will follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Step 1: Calculate the value of the expression inside the parentheses.
Since any number raised to the power of zero is equal to 1, we have:
12^0 = 1.

So, the expression becomes:
-4(3 + 1) + 15^0

Step 2: Simplify the addition inside the parentheses.
3 + 1 = 4.

The expression now becomes:
-4(4) + 15^0

Step 3: Simplify the exponent.
Since any number raised to the power of zero is equal to 1, we have:
15^0 = 1.

The expression now becomes:
-4(4) + 1

Step 4: Perform the multiplication first.
-4 multiplied by 4 equals -16.

The expression now becomes:
-16 + 1

Step 5: Perform the addition.
-16 plus 1 equals -15.

Therefore, the final result is:
-15.

To solve the expression -4(3+12^0) + 15^0, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

Step 1: Simplify within parentheses:
12^0 means raising 12 to the power of 0. Any number raised to the power of 0 is always equal to 1. Therefore, 12^0 is equal to 1.
-4(3+1) + 15^0

Step 2: Perform addition within parentheses:
3 + 1 equals 4.
-4(4) + 15^0

Step 3: Simplify exponent:
15^0 means raising 15 to the power of 0. As mentioned earlier, any number raised to the power of 0 is always equal to 1.
-4(4) + 1

Step 4: Perform multiplication:
-4 multiplied by 4 equals -16.
-16 + 1

Step 5: Perform addition:
-16 plus 1 equals -15.

Therefore, the solution to the expression -4(3+12^0) + 15^0 is -15.
