Answer:

There will be three significant figures in the answer.

Explanation:

When multiplying or dividing measurements (numbers), the result must have the same number of significant figures as the number in the problem with the fewest significant figures.

#101.7xx5.45=554.265# on the calculator. However, you would record the result as #554# because #5.45# has the least significant figures, so the result must be rounded to three significant figures.
