Question

if(3/4)^5x =1 then x is equal to​

Answer 1

Answer:

22−log23

11−log43

2log232log23−1

Answer :

C

Solution :

3x=4x−1

Taking log3 on both sides, we get

⇒xlog33=(x−1)log43

⇒x=2log32⋅x−log34

⇒x(1−2log32)=−2log32

⇒x=2log322log32−1

⇒x=11−12log32=11−1log34=11−log43=22−log23

⇒11−12log23=11−log43
