Question

Solve the expression 2(1.6^0+7)−4.9^0

Answer 1

To solve the expression, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

We start by evaluating the expression inside the parentheses: 1.6^0 = 1 (any number raised to the power of 0 equals 1).

Now we substitute this value back into the original expression: 2(1 + 7) - 4.9^0.

Next, we simplify the expression inside the parentheses: 1 + 7 = 8.

Now our expression becomes: 2(8) - 4.9^0.

We simplify the multiplication: 2 * 8 = 16.

Now our expression becomes: 16 - 4.9^0.

Finally, we evaluate the experssion 4.9^0: any number (except 0) raised to the power of 0 equals 1. Therefore, 4.9^0 = 1.

Now our expression becomes: 16 - 1.

And the final solution is 15.
