Solve the expression 2(1.6^0+7)−4.9^0

Answer 1

To solve this expression, we need to follow the order of operations (also known as PEMDAS): Parentheses, Exponents, Multiplication/Division (from left to right), and Addition/Subtraction (from left to right).

First, we solve the exponent 0. Any number (except 0) raised to the power of 0 is equal to 1. Thus, 1.6^0 equals 1.

Now we can simplify the expression:
2(1+7)−4.9^0
= 2(8)−4.9^0
= 16−4.9^0

Since 4.9^0 is also equal to 1 (any number raised to the power of 0 is 1), the expression becomes:
16−1

Finally, we subtract 1 from 16:
16−1 = 15

Therefore, the solution to the expression 2(1.6^0+7)−4.9^0 is 15.
