b) 7.154 × 10^16 g
c) 7.154 × 10^2 g
d) 7.154 × 10^10 g

Answer 1

To solve the problem, convert both values to grams and subtract. The answer is 7.54 × 10^6 g.

Step-by-step explanation:

To perform the operation (7.154 × 109 cg) - (6.4 × 107 g), we need to convert both values to the same unit, which is grams.

First, convert 7.154 × 109 cg to grams:

7.154 × 109 cg = 7.154 × 109 × 0.01 g = 7.154 × 107 g.

Next, subtract 6.4 × 107 g from 7.154 × 107 g:

7.154 × 107 g - 6.4 × 107 g = 0.754 × 107 g = 7.54 × 106 g.

So, the answer is 7.54 × 106 g.
