Question

2.9617x10^13-3.98x10^11

Answer 1

To subtract the numbers \( 2.9617 \times 10^{13} \) and \( 3.98 \times 10^{11} \), we need to express both numbers with the same exponent.

The number \( 3.98 \times 10^{11} \) can be rewritten in terms of \( 10^{13} \):
\[
3.98 \times 10^{11} = 0.0398 \times 10^{13}
\]

Now, we can perform the subtraction:
\[
2.9617 \times 10^{13} - 0.0398 \times 10^{13} = (2.9617 - 0.0398) \times 10^{13}
\]
Calculating the subtraction:
\[
2.9617 - 0.0398 = 2.9219
\]

Thus, the result is:
\[
2.9219 \times 10^{13}
\]

Therefore, \( 2.9617 \times 10^{13} - 3.98 \times 10^{11} = 2.9219 \times 10^{13} \).
