Answer:

-3

Step-by-step explanation:

Simplify the following:

(-9 (-5) - 9)/(-12)

-9 (-5) = 45:

(45 - 9)/(-12)

| 3 | 15

| 4 | 5

- | | 9

| 3 | 6:

36/(-12)

The gcd of 36 and -12 is 12, so 36/(-12) = (12×3)/(12 (-1)) = 12/12×3/(-1) = 3/(-1):

3/(-1)

Multiply numerator and denominator of 3/(-1) by -1:

Answer: -3

How to use exponents instead of logs

PSYCHO15rus [73]

Answer:

Convert into same base

Step-by-step explanation:

Convert both sides into same bases and equate the powers to solve for the variable.

Example:

8^x = 32

You can either use logs to bring the power down or convert both sides into the same base

8 = 2³

8^x = (2³)^x = 2^(3x)

32 = 2⁵

2^(3x) = 2⁵

3x = 5

x = 5/3

x = 1⅔
