2(1.6⁰+7)−4.9⁰=

Answer 1

To solve the expression \( 2(1.6^0 + 7) - 4.9^0 \), we need to calculate each part step by step.

1. Calculate \( 1.6^0 \): Any non-zero number raised to the power of 0 is 1. Therefore: \[ 1.6^0 = 1 \]

2. Calculate \( 4.9^0 \): Similarly: \[ 4.9^0 = 1 \]

3. Substitute the values into the expression: Now substituting these values into the expression: \[ 2(1 + 7) - 1 \]

4. Calculate inside the parentheses: \[ 1 + 7 = 8 \]

5. Multiply by 2: \[ 2 \times 8 = 16 \]

6. Subtract 1: \[ 16 - 1 = 15 \]

Therefore, the final result of the expression \( 2(1.6^0 + 7) - 4.9^0 \) is: \[ \boxed{15} \]
