Solve for x Dont have to state answer in decimal 4 ln 5x 5

Solve for x. Dont have to state answer in decimal. 4 ln (5x) + 5 = 2 2(5)^3x - 5 = 18

b) 4ln(5x) +5 =2

4ln(5x) +5 -5 =2-5

4ln(5x) =-3

4ln(5x) /4 =-3/4

ln(5x) =-3/4

(5x) =e^-3/4

(5x)/5 e^-3/4/5

x=(1/5)e^-3/4

c)2(5)^3x-5 =18

2(5)^3x-5/2=18/2

(5)^3x-5=9

3x-5 =ln₅9

3x-5+5 =5+ln₅9

3x =5+ln₅9

3x/3 =(5+ln₅9)/3

x =(1/3)(5+ln₅9)
