Question

Simplify 0.2×0.03055​

Answer 1

`0.2 = (2)/(10) = (2)/(10 ^(1) ) = 2 * {10}^( - 1) \\ 0.03055 = (3055)/(100000) = \frac{3055}{ {10}^(5) } = 3055 * {10}^( - 5) \\ 0.2 * 0.03055 = 2 * {10}^( - 1) * 3055 * {10}^( - 5) \\ = 2 * 3055 * {10}^( - 1 + ( - 5)) \\ = 2 * 3055 * 10^( - 1 - 5) \\ = 2 * 3055 * {10}^( - 6) \\ = 6110 * {10}^( - 6) \\ = \frac{6110}{ {10}^(6) } \\ = (6110)/(1000000) \\ = 0.006110`
