Question

5raise to pawer x-1 multiply by 3 raise to power 2x-8=225

Answer 1

Answer:

5

Step-by-step explanation:

5^x-3 * 3^2x-8 = 225

5^x-3 * 3^2x-8 = 15^2

5^x-3 * 3^2x-8 = 5^2 * 3^2 {5^2 * 3^2 gives you 15^2}

Now, compare the common values

x-3=2 ; 2x-8=2

x=5; x=5

Thus, x=5

I think you have copied your question wrong. It is not possible for x-1 to be the power of 5 in this question because it will not produce the required result

Hope this helps
