Use a calculator to find approximations of the common logarithms. (a) $\log (714.1)$ (b) $\log (71.41)$ (c) $\log (7.141)$

Step 1 ：The common logarithm of a number is the power to which the number 10 must be raised to obtain that number. In other words, if \(y = \log_{10}(x)\), then \(10^y = x\).

Step 2 ：Use a calculator to find approximations of the common logarithms.

Step 3 ：\(\log (714.1)\) is approximately 2.853759033074769

Step 4 ：\(\log (71.41)\) is approximately 1.8537590330747686

Step 5 ：\(\log (7.141)\) is approximately 0.8537590330747687

Step 6 ：Final Answer: (a) \(\log (714.1) \approx \boxed{2.854}\)

Step 7 ：Final Answer: (b) \(\log (71.41) \approx \boxed{1.854}\)

Step 8 ：Final Answer: (c) \(\log (7.141) \approx \boxed{0.854}\)
