48. Solve the following equations for x.
(a) 3^(2x-1)= 9
(b) 5^(x^2+8)= 125^(2x)
(c) e^(4x-9)=1/e
(d) (e^4)^x * (e^x)^2= e^12
49. Find the value of each expression without using acalculator.
(a) log2 32
(b) log3 1
(c) log6 (1/25)
(d) log1/2 8
(e) ln3?e
(f) log25 5
50. Find the domain of each function.
(a) y = 5 - 2ln(x/3
Please answer these problems. I HAVE THE SOLUTIONS I just need the workings because I don't understand how to get there
The answers are:
A) 1/2 ln(4/3)
B) 1/2 ln(4x^2 + 12x - 40) + 9/14 ln(1/7(2x+10)) - 9/14 ln(1/7(2x-4)) + C
PLEASE as soon as you can show the WORKINGS using PARTIAL FRACTIONS for these answers. Thanks.
