Solve the expression 2(1.60+7)−4.9^0 .(1 point)

Question

2(1.60+7)−4.9^0=

Answer 1

To solve the expression \( 2(1.60 + 7) - 4 \cdot 9^0 \), we can break it down step-by-step:

1. Calculate \( 1.60 + 7 \): \[ 1.60 + 7 = 8.60 \]

2. Multiply the result by 2: \[ 2(8.60) = 17.20 \]

3. Calculate \( 9^0 \): \[ 9^0 = 1 \quad \text{(any non-zero number to the power of 0 is 1)} \]

4. Multiply this result by 4: \[ 4 \cdot 9^0 = 4 \cdot 1 = 4 \]

5. Now, subtract this from the previous result: \[ 17.20 - 4 = 13.20 \]

Therefore, the final result is: \[ \boxed{13.20} \]
