Solve the expression

Question

15×8^0/5 + 4 (7^0 - 6) =

Answer 1

To solve the expression \( 15 \times 8^0 / 5 + 4 (7^0 - 6) \), we will evaluate each part step by step.

1. Evaluate \( 8^0 \) and \( 7^0 \): \[ 8^0 = 1 \quad \text{(any non-zero number raised to the power of 0 is 1)} \] \[ 7^0 = 1 \]

2. Substituting the values into the expression: \[ 15 \times 1 / 5 + 4 (1 - 6) \] This simplifies to: \[ 15 / 5 + 4 (-5) \]

3. Calculate \( 15 / 5 \): \[ 15 / 5 = 3 \]

4. Calculate \( 4 (-5) \): \[ 4 \times -5 = -20 \]

5. Combine the results: \[ 3 - 20 = -17 \]

Thus, the final result of the expression is: \[ \boxed{-17} \]
