From your guys help, THANKS I was able to understand questions better I was hoping someone would check my answers:(adsbygoogle = window.adsbygoogle || []).push({});

for : evaluate the following logarithms:

log22^log55 I got:

log22=2^1 log55=5^1

=1 =1

therefore 1^1=1 is that correct???

Another one: solve the following logarithm equation:

log25=log2(x+32)-log2x

I got:

log25=log2(x+32)-log2x

5=log2 (x+32)/x

x+32=(5)(x)

x+32-5x

4x-32=0

x-8

therefore x=8.... is that right??????

Next: Determine the deriviative of the following functions:

d) y=2x^3 e^4x

well I figured out how to do the e^4x part it would be: 4e^4x so would the derivative be 6x^2 4e^4x????

e.) determine the derivative:

y=sq root(x^3+e^-x +5) I got:...

y=(x^3 + e^-x + 5)^1/2

dy/dx= 1/2 (x^3 + e^-x + 5)^-1/2 (3x^2-1e^-x) Now Im stuck... Is what I have right soo farr and if so can someone help me to continue.
