Step-by-step explanation:

a. 14.8 = 10 + 4 + 0.8

           = 1 x 10 + 4 x 1 + 8 x \frac{1}{10}

           = 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 \frac{1}{10}  + 5 x \frac{1}{100}

           = 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 \frac{1}{1000}  

                  = 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 \frac{1}{10}  + 5 x \frac{1}{1000}  

                  = 7 x 10² + 1 x 10¹ + 8 x 10⁰ + 7 x 10⁻¹ + 5 x 10⁻³
