Question 203958: Hi all, I was hoping someone could help me in answering the following 2 problems. They are two similiar problems bbut they are seperate problems and are not related to eachother.
1. Make t the subject of the equation y = sqrt(8t + 3)
2. Make x the subject of the equation y = 3e^(2x).
Any help with steps would be most appreciated.
Thanks, -Nick.

1. Make t the subject of the equation y = sqrt(8t + 3)
y =
Square both sides:
y^2 = 8t + 3
Subtract 3 from both sides
y^2 - 3 = 8t
Divide both sides by 8
= t

:
2. Make x the subject of the equation y = 3e^(2x)
y =
Divide both sides by 3
=
find the natural log of both sides
=
log equiv of exponents:
=
natural log of e is 1
= 2x
divide both sides by 2
= x
