Math Practice Test For You...1

 

for me or for you

 

This is for anyone here seeking extra math practice. So, not for me.

 

Look at the link below. Which of the following courses have you taken and/or not taken?

List of Math Courses

 

you should be able to do it

at least, try

 

I can do this easily. It's not for me. I posted test questions from the David Cohen textbook as practice for anyone seeking extra practice.

 

A.

1/125=5^-3

-3=log(5,(1/125))

B.

e^0=1

0=log(e,1) or 0=ln(1)

C.

5^x=6

x=log(5,6)

D.

e^(3t)=8
3t=ln(8)
t=ln(2^3)/3
t=(3ln(2))/3

t=ln(2)

write equation in log form

A.
9=3^2
2=log(3,9)

B.
1000=10^3

3=log(10,1000)

C.
7^3=343
3=log(7,343)

D.
sqrt(2)=2^(1/2)
1/2=log(2,sqrt(2))

write an equation in exponential form

A.
log(2,32)=5
2^5=32

B.
log(10,1)=0

10^0=1

C.

log(e, sqrt(e))=12-> false, should be 1/2

log(e, sqrt(e))=1/2

log(e, e^(1/2))=12

e^(1/2)=e^(1/2)

 

Solving lots of different questions as you did helps visiting students. Your math work will help a high school or college student preparing for an upcoming exam. Remember: I am reviewing precalculus and precalculus only.

If you do not see a section number listed at the very top of the page, I am not seeking help; it is just a general problem(s) to help visiting students. Moving forward, I indicate precisely why the thread was posted. For example, at the very top you will see PRACTICE MATH PROBLEMS FOR VISITING STUDENTS AND/OR MATH ENTHUSIASTS. You are a math tutor, former teacher and so I think of you as a math enthusiast. Feel free to answer any question you like or any thread you find interesting. Your math work shown also makes good study notes.
