1. 9^y+5(3^y-10)=0
2. 3^2x=16-2(3^x+1)
3. 2^2x=2^x+1+15
Thank you
A rough guide... Use suitable substitution for all the Qn.
1. Let u = 3^y
2. Let u = 3^x
3. Let u = 2^x
Then you can carry on solving using quadratic equation.
Try :smile:

Give you a guide to start. :smile:

Move one item to the right.
Take lg both side.
Use power law to bring the power down.
Expand and you will be able to group the lg x together and solve.
Try it :smile:
