Answer 1

(a) 0.000 000 603

(b) 0.009

(c) 0.000 000 000 000 002 27

Explanation:

(a) Move the decimal point seven places to the left.

6.03 × 10⁻⁷ = 0.000 000 603

(b) Align the decimal points over each other, then subtract

0.0012

-0.0003

0.0009

(c) 7.078 × 10⁻⁶ × 3.21 × 10 ⁻¹⁰

= (7.078 × 3.21) × (10⁻⁶ × 10 ⁻¹⁰) Collected the exponents

= 22.7 × 10⁻¹⁶ Handled the parentheses separately

= 2.27 × 10 × 10⁻¹⁶ Converted 22.7 to a power of 10

= 2.27 × 10⁻¹⁵ Added the exponents

= 0.000 000 000 000 002 27
