## anonymous one year ago What is the solution of Log_2x+3^125=3?

1. Nnesha

$\huge\rm log_{2x+3}125=3$ like this ?

2. anonymous

yes

3. anonymous

log(2x-3) 125 = 3 (2x - 3)^3 = 125 ........log(baseA)B = x , then A^x = B Taking cube roots on both sides 2x - 3 = 5 2x = 5+3 2x = 8 x = 4

4. Nnesha

alright so you have to convert log to exponential form here is an example |dw:1439574126077:dw|

5. Nnesha

2x+3 is base so convert log to exponential form
