What is 3log2 x-(log2 3-log2(x+4)) written as a single logarithm?
zloy xaker [14]
Answer:
log₂(\frac{x^2(x+4)}{3})

Explanation:
Before we begin, remember the following:
logₐ(x) - logₐ(y) = logₐ(\frac{x}{y})
alog(x) = log(xᵃ)

Now, for the given we have:
3 log₂(x) - (log₂3 - log₂(x+4))
log₂(x²) - log₂(\frac{3}{x+4})

log₂(\frac{x^2}{ \frac{3}{x+4} }) = log₂(\frac{x^2(x+4)}{3})

Hope this helps :)

storchak [24]

33489 = 32×612

3948 = 22×3×7×47

3949 = 11×359

GCD = 1

33489 / 1 = 33489

3948 / 1 = 3948

3949 / 1 = 3949

Does anyone have any Idea how to solve this?
Mariulka [41]

Answer:

x = 12

Step-by-step explanation:

Remark

These two angles are corresponding angles and as such, they are equal.

Equation

8x+ 36 = 5x + 72

Solution

Subtract 5x from both sides

8x - 5x + 36 = 5x - 5x + 72          Combine like terms.

3x + 36 = 72                                 Subtract 36 from both sides

3x + 36 - 36 = 72 - 36                  Collect like terms

3x = 36                                          Divide by 3

3x/3 = 36/3                                   Divide

x = 12                                             Answer
