Okay this is a precalculus question...how would you answer 5^2+3x
please help! the 2 and 3x are in the exponent..i have problems with these kinda of questions, where there are multiple exponents with a variable...any more examples and answers woul be great too! thank you so much!
 
5^(2+3x) is the same as (5^2)(5^3x) because of laws of exponents. Therefore, it simplifies to 25(5)^3x

Hope this helps
