15⋅8^0/5 + 4(7^0 − 6)= __

1 answer

Let's solve the expression step by step.

Given:

\[ 15 \cdot 8^0 / 5 + 4(7^0 - 6) \]

  1. Calculate \( 8^0 \): \[ 8^0 = 1 \]

  2. Substitute into the expression: \[ 15 \cdot 1 / 5 + 4(7^0 - 6) \]

  3. Now calculate \( 15 \cdot 1 / 5 \): \[ 15 / 5 = 3 \]

  4. Next, calculate \( 7^0 \): \[ 7^0 = 1 \]

  5. Substitute into the expression: \[ 4(1 - 6) \]

  6. Calculate \( 1 - 6 \): \[ 1 - 6 = -5 \]

  7. Now multiply: \[ 4 \cdot (-5) = -20 \]

  8. Now put everything together: \[ 3 + (-20) = 3 - 20 = -17 \]

Therefore, the final answer is:

\[ \boxed{-17} \]
