Express in Same Base: We need to express both sides of the equation in terms of the same base to solve for 'a'. The square root of 5 can be written as 5 raised to the power of 21. So, we rewrite the equation as 5a=521.
Set Exponents Equal: Since the bases are the same (both are 5), we can set the exponents equal to each other. This gives us the equation a=21.
Final Value of 'a': We have found the value of 'a' that satisfies the equation 5a=5. There is no need for further calculation or simplification.
