Question

Can someone see if I got these correct?

1. Solve log5 x = 3.
x = 125

2. log3 (x - 4) > 2.
x > 13

3. Evaluate log7 49.
log7 49 = 2

4. Solve log3 x = 4.
x = 81

5. The graph of a logarithmic function y = 3^x is a reflection of x = 3^y over the line y = 0.
False

6. Evaluate log7 7^5.
=5

7. Does log5 (12p) = log5 12 + log5 p?
Yes

8. solve the equation, log4 z + log4 8 = log4 24. z = 16

9. Solve In (x - 6)< - 3.
x < 6 + ^e(-3)

10. Write an equivalent expression for x if e^x+3 = 6.
x = -3 + In 6

Answer 1

#8. 8z = 24, so z=3 (see question 7!)

#10 correct, if you meant e^(x+3) = 6
as you wrote it, x = ln 3

The others are all good.

Answer 2

2logx + log2 =2
