Step-by-step explanation:

∛-25 × ∛5

= ∛-75

= ∛(-5)^3

= - 5

a

Step-by-step explanation:

(-25)^⅓ × 5^⅓

(-25 × 5)^⅓

(-125)^⅓

(-5)³^⅓

-5

The answer is D

Step-by-step explanation:

Factor and set each set equal to zero to get x=0,2,-1,1

A) 3log(x)+2log(y)-4log(z)

You should get the app Socratic it will help you a lot.

B

Step-by-step explanation:

(-2x³ - 4x²+ 9x² + 18x - 19x - 38 + 40)

÷ (x + 2)

[-2x²(x+2) + 9x(x+2) - 19(x+2) + 40]

÷ (x+2)

-2x² + 9x - 19 + 40/(x+2)

b

Step-by-step explanation:

(-2x³ - 4x²+ 9x² + 18x - 19x - 38 + 40)

÷ (x + 2)

[-2x²(x+2) + 9x(x+2) - 19(x+2) + 40]

÷ (x+2)

-2x² + 9x - 19 + 40/(x+2)

B

Step-by-step explanation:

2 || 1   -   4     6    -   4

              2    -4       4

     1       -2    2

x^2 - 2x + 2 with no remainder.

Looks like the answer is B

Note: Note that the two in x - 2 changes sign. That always happens when using synthetic division as long the number in front of the x is positive.

Because it is a fraction ( division) rewrite as:

log (5x) - log (4y)

Rewrite log 5x as log 5 + log x

Rewrite log 4y as log 4 + log y

Now you have log 5 + log x  - log 4 + log y

Apply distributive property:

log 5 + log x - log 4 - log y

The answer is B.

D

Step-by-step explanation:

x¹³ - 2x¹² - x¹¹ + 2x¹⁰ = 0

x¹⁰(x³ - 2x² - x + 2) = 0

x¹⁰ [x²(x - 2) - (x - 2)] = 0

x¹⁰(x² - 1)(x - 2) = 0

x = 0 (multiplicity 10)

x = 1

x = -1

x = 2

see explanation

Step-by-step explanation:

Using the coefficients of the polynomial and evaluating for h = - 3

- 3 | 1   - 4   - 9   36

      ↓   - 3   21   - 36

       1   - 7   12   0 ← remainder

Since remainder is 0 then (x + 3) is a factor, so

y = (x + 3)(x² - 7x + 12)

To factor the quadratic

Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (- 7)

The factors are - 4 and - 3, since

- 4 × - 3 = + 12 and - 4 - 3 = - 7, then

x² - 7x + 12 = (x - 4)(x - 3), and

y = (x + 3)(x - 4)(x - 3)
