Answer 1

To solve the expression \( 15 \cdot 8^0 / 5 + 4(7^0 - 6) \), we can break it down step by step.

1. Calculate \( 8^0 \) and \( 7^0 \):

   • Any non-zero number raised to the power of 0 is 1.
   • Therefore, \( 8^0 = 1 \) and \( 7^0 = 1 \).

2. Substitute those values into the expression: \[ 15 \cdot 1 / 5 + 4(1 - 6) \]

3. Then, simplify the expression:

   • First part: \[ 15 / 5 = 3 \]
   • Second part: \[ 1 - 6 = -5 \quad \text{so} \quad 4(-5) = -20 \]

4. Now combine the results: \[ 3 + (-20) = 3 - 20 = -17 \]

Thus, the final answer is \(-17\).

So the response is:

−17
