Q. Express the given expression as an integer or as a fraction in simplest form.log(102)Answer:
Identify base and argument: Identify the base of the logarithm and the argument.The base of the logarithm is 10, which is the common logarithm base, and the argument is 102.
Apply logarithm power rule: Apply the logarithm power rule.The power rule of logarithms states that logb(an)=n⋅logb(a), where b is the base, a is the argument, and n is the exponent.For our expression, log(102) can be rewritten as 2⋅log(10).
Evaluate log(10): Evaluate log(10).Since the base of the logarithm is 10 and the argument is also 10, log(10) is equal to 1 because 101=10.
Multiply exponent by log(10): Multiply the exponent by the value of log(10). Now we have 2×log(10) which is 2×1. This simplifies to 2.
