Math Problem Statement

is this correct log(base a)(a^x) = x

Solution

Yes, the equation loga(ax)=x\log_a(a^x) = x is correct.

This is a fundamental property of logarithms known as the logarithm-exponential identity. Here's why it holds true:

Explanation:

  1. The logarithm loga(y)\log_a(y) is defined as the power to which the base aa must be raised to obtain the number yy. In other words, loga(y)=x\log_a(y) = x implies that ax=ya^x = y.

  2. Given the expression loga(ax)\log_a(a^x), you're essentially asking, "To what power must aa be raised to get axa^x?"

  3. Since aa raised to the power xx is simply axa^x, the answer is xx. Therefore: loga(ax)=x\log_a(a^x) = x

This property is true for any positive base aa (where a1a \neq 1) and any real number xx.
