Question

1.7 times 10^11 minus 7.4 times 10^10

Answer 1

To perform the calculation \(1.7 \times 10^{11} - 7.4 \times 10^{10}\), it helps to express both terms with the same exponent.

First, we can express \(1.7 \times 10^{11}\) in terms of \(10^{10}\):

\[
1.7 \times 10^{11} = 1.7 \times 10^{10} \times 10 = 17.0 \times 10^{10}
\]

Now, we can rewrite the expression:

\[
17.0 \times 10^{10} - 7.4 \times 10^{10}
\]

Next, we can subtract the coefficients:

\[
(17.0 - 7.4) \times 10^{10} = 9.6 \times 10^{10}
\]

So, the result is:

\[
9.6 \times 10^{10}
\]
