Answer:

4ln [\frac{x^2 (x^3-1)}{x-5}]

Step-by-step explanation:

For this case we have the following expression:

4[ln(x^3-1) +2ln(x) -ln(x-5)]

For this case we can apply the following property:

a log_c (b) = log_c (b^a)

And we can rewrite the following expression like this:

2 ln(x) = ln(x^2)

And we can rewrite like this our expression:

4[ln(x^3-1) +ln(x^2) -ln(x-5)]

Now we can use the following property:

log_c (a) +log_c (b) = log_c (ab)

And we got this:

4[ln(x^3-1)(x^2) -ln(x-5)]

And now we can apply the following property:

log_c (a) -log_c (b) = log_c (\frac{a}{b})

And we got this:

4ln [\frac{x^2 (x^3-1)}{x-5}]

And that would be our final answer on this case.

Can someone please help as I'm not sure how to tackle this step by step? Especially question b, d, g, j, k, l. Not how sure to d
Arisa [49]

Step-by-step explanation:

√a = 1√a so we can solve them easily:

b) 3√7 -√7= 3√7 - 1√7 =( 3-1)√7= 2√7

d) 5√6 - 2√6+√6= (5-2+1)√6 = 4√6

g) √2+2√2= 3√2

j) √5+5√5 - 3√5 = 3√5

k) 2√3 + √3 - 5√3= -2√3

I) 5√11 + 7√11 - √11 = 11√11

-3(x - 1) 7x=27 You have to Distribute it to get the answer​
Finger [1]
First you would distribute the -3

-3x+1+7x=27

Combine like terms

4x+1= 27

Minus 1 on both sides

4x= 26

Divide by 4

X= 6.5

(3.rº – 7x + 2) - (2x² – 4x + 5)
Vladimir79 [104]

Answer:

choice C: x2 -3x -3

Step-by-step explanation:

(3x^2-7x+2)-(2x^2-4x+5)

becomes

3x^2-7x+2 -2x^2+4x-5

adding

3x^2-2x^2 -7x+4x +2-5

which is

x^2 -3x -3
