Problem 50P

Round each number to three significant figures.

(a) 10,776.522

(b) 4.999902 × 106

(c) 1.3499999995

(d) 0.0000344988

                                                               Step by step solution

Step 1 of 4

a)

The following rules can be followed to round up the final answer to the significant figures.

          * Round down if the last digit dropped is 4 or less

          * Round up if the last digit dropped is 5 or more.

The given value - 10,776.522.

We have to move the decimal point to the left 4 decimal places to obtain a number between 1 and 10.

Hence, we have moved the decimal point to 4 places, the exponent used here is 4.

The last digit is less than five. We have to round it up.

Therefore rounded to three significant figures.
