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

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)
