Question

Solve the expression 2(1.6^0 +7) - 4.9^0

Answer 1

To solve the expression \( 2(1.6^0 + 7) - 4.9^0 \), we first need to evaluate the terms involving the exponent of 0.

Recall that any non-zero number raised to the power of 0 equals 1. Thus:

\[
1.6^0 = 1
\]
\[
4.9^0 = 1
\]

Now substituting these values back into the expression:

\[
2(1 + 7) - 1
\]

Perform the addition inside the parentheses:

\[
1 + 7 = 8
\]

Now we have:

\[
2 \times 8 - 1
\]

Next, perform the multiplication:

\[
2 \times 8 = 16
\]

Finally, perform the subtraction:

\[
16 - 1 = 15
\]

Thus, the final answer is:

\[
\boxed{15}
\]
