Chapter 1, Problem 25P

The following times are given in seconds. Use metric prefixes to rewrite them so the numerical value is greater than one but less than 1000. For example, $7.9\times {10}^{-2}\text{s}$ could be written as either $\text{7}\text{.9cs}$ or $\text{7}\text{.9ms}$ . (a) $9.57\times {10}^5\text{ s}$ : (b $\text{0}\text{.045s}$ ; (c) $5.5\times {10}^{-7}\text{ s}$ ; (d) $3.16\times {10}^7\text{ s}$ .
