Explain why the exponents cannot be added in the product 12 to the power of three times 11 to the power of 3
egoroff_w [7]
Normally, we could add exponents.
however, that only is possible when the bases are the same
recall what exponents mean

12³=12*12*12


so we cannot add exponents for 12³*11³ because that means 12*12*12*11*11*11
it would not equal 12⁶ or 11⁶



or you  could refer to the rule
(x^a)(x^b)=x^{a+b}
notice when x=x then we can add the bases


fun fact below
we can reverse a previous exponential rule like this
since (ab)^c=(a^c)(b^c) then (a^c)(b^c)=(ab)^c
therefor
12^3*11^3=(12*11)^3



we can't add the exponents because the bases are not the same

2. Use the Distributive Property to determine which of the following statements is equivalent to 5(6-2).

When you distribute, that means you multiply everything on the outside of the parentheses by everything on the inside.

5 (6-2)

F(x) = 2/x, g(x) = |x| -1 <br><br> what is the domain of (fog) (x)?<br><br> WILL MARK BRAINLIEST
DIA [1.3K]

Answer:

x≠-1,1

Step-by-step explanation:

f(g(x)) is a composition where g(x) is is substituted for x in f(x).

Recall, f(x) is 2/x. So we write 2/|x|-1. This places x in the denominator and 0 cannot be in the denominator x. Any value of x that makes the denominator 0 will not be in the domain.

|x|-1=0

|x|=1

x=1,-1

4. k(x) × g(x) × f(x)​
Vikentia [17]

k(x) \times f(x)

(2x + 5) \times (x - 1)

2 x(x - 1) + 5(x - 1)

({2 x }^{2}  - 2x) + (5x - 5)

{2x}^{2}  - 3x - 5

________________________________

k(x) \times g(x) \times f(x)

g(x) \times (k(x) \times f(x))

({6x   }^{2}  - 4x +  {3x}^{4} ) \times ( {2x}^{2}  - 3x - 5)

{6x}^{2}  ( {2x}^{2}  - 3x - 5) - 4x ( {2x}^{2}  - 3x - 5) +  {3x}^{4}  ( {2x}^{2}  - 3x - 5)

12 {x}^{4}  - 18 {x}^{3}  - 30 {x}^{2}  -  {8x}^{3}  - 12 {x}^{2}  - 20x +  {6x}^{6}  - 9x {}^{5}  -  {15x}^{4}
