Question

Find x , when 5^x-2 * 3^x-3 = 135

Answer 1

Here no values to x will get the answer
because by trial and error
if we put x=1 then power will be negative and will not get the value and same in the case of x=2
if we put x=3 then the value is 5
put x=4 then value is 25*3=75
if x is morethan 4 then the term 5^(x-2) only have a value from 125 and above
so we will not get the answer as 135
so please check the problem once again and correct if the question is not as you asked
thank you
