Answers
Step-by-step explanation:
a. 14.8 = 10 + 4 + 0.8
= 1 x 10 + 4 x 1 + 8 x
= 1 x 10¹ + 4 x 10⁰ + 8 x 10⁻¹
b. 25.75 = 20 + 5 + 0.7 + 0.05
= 2 x 10 + 5 x 1 + 7 x + 5 x
= 2 x 10¹ + 5 x 10⁰ + 7 x 10⁻¹ + 5 x 10⁻²
c. 695.008 = 600 + 90 + 5 + 0.008
= 6 x 100 + 9 x 10 + 5 x 1 + 8 x
= 6 x 10² + 9 x 10¹ + 5 x 10⁰ + 8 x 10⁻³
d. 718.705 = 700 + 10 + 8 + 0.7 + 0.005
= 7 x 100 + 1 x 10 + 8 x 1 + 7 x + 5 x
= 7 x 10² + 1 x 10¹ + 8 x 10⁰ + 7 x 10⁻¹ + 5 x 10⁻³
a. 14.8 = 10 + 4 + 0.8
= 1 x 10 + 4 x 1 + 8 x
= 1 x 10¹ + 4 x 10⁰ + 8 x 10⁻¹
b. 25.75 = 20 + 5 + 0.7 + 0.05
= 2 x 10 + 5 x 1 + 7 x + 5 x
= 2 x 10¹ + 5 x 10⁰ + 7 x 10⁻¹ + 5 x 10⁻²
c. 695.008 = 600 + 90 + 5 + 0.008
= 6 x 100 + 9 x 10 + 5 x 1 + 8 x
= 6 x 10² + 9 x 10¹ + 5 x 10⁰ + 8 x 10⁻³
d. 718.705 = 700 + 10 + 8 + 0.7 + 0.005
= 7 x 100 + 1 x 10 + 8 x 1 + 7 x + 5 x
= 7 x 10² + 1 x 10¹ + 8 x 10⁰ + 7 x 10⁻¹ + 5 x 10⁻³
