(a) 89.3 × 77.0 × 0.08

(b) (5.01 × 105) ÷ (7.8 × 102)

(c) 4.005 × 74 × 0.007

(d) 453 ÷ 2.031

Solution 58P

Step 1:

Perform each calculation to the correct number of significant figures.

(a) 89.3 × 77.0 × 0.08 = 550.088

The significant figures will be = 5105

(b) (5.01 × 105) ÷ (7.8 × 102)

(5.01 × 105) = 526.05

Thus the significant figure will be...
