Logarithm problems

1. If 5x - 17 = -x + 7, then x = ?
Options
A. 4
B. 5
C. 7
D. 9

Also asked in:

Correct Answer: 4

Explanation:

Given equation 5x-17 = -x+7

Add 1x to each side of the equation

5x-17+x = -x+7+x

6x=24

x=4

2. If A = log321875 and B = log2432187 , then which one of the following is correct?
Options
A. A
B. A=B
C. A>B
D. can't be determined

Also asked in:

Correct Answer: A=B

Explanation:

Given $A = \frac{\log_{3} (2187)}{5} a n d B = \log_{243} (2187)$

$B = \log_{3^{5}} (2187) = \frac{\log_{3} (2187)}{5}$

=> A

Therefore, A = B
