Question 6 (1 point) (01.03 LC) What is the value of 5 to the power of 4 over 5 to the power of 6? (1 point) a 1 over 25 b 1 ove
Vlad [161]

Answer:

a 1 over 25

Step-by-step explanation:

Problem Statement:

     What is the value of  \frac{5^{4} }{5 ^{6} } ?

To solve this problem, we must familiarize ourselves with the concept of exponents and rules that guides them.

Exponents are used by scientists to report higher orders of a number.

Such large and often recurring expression is usually made up of a base and an exponent value.

The exponent value is the power of the base;   for example, 4³ has 4 as its base and 3 as the exponent.

Several rules guides solving an exponent, to this problem, the most applicable one is :

                            \frac{x^{a} }{x^{b} }  =  x^{(a-b)}

                           \frac{5^{4} }{5 ^{6} }   =  5^{4-6}  

                                 = 5^{-2}

                                 = \frac{1}{25}                                  

Therefore the solution is 1 over 25

Zinaida [17]

Answer:

  x^3+3x^2+9x+27

Step-by-step explanation:

\dfrac{x^4-81}{x-3}=\dfrac{(x^2-9)(x^2+9)}{x-3}=\dfrac{(x-3)(x+3)(x^2+9)}{(x-3)}\\\\=(x+3)(x^2+9)=x^3+3x^2+9x+27

_____

The factoring of the difference of squares is used (twice):

  a² -b² = (a -b)(a +b)

Multiply the polynomial 3x2+4x+4)(2x-4)​
Lorico [155]

Answer:

\large \boxed{6x^{3} - 4x^{2} - 8x -16}

Step-by-step explanation:

(3x² + 4x + 4)(2x - 4)

The easiest method is probably to use long multiplication.

3x²  + 4x   + 4

<u>2x   -  4             </u>

6x³ +  8x² +  8x

<u>       - 12x² - 16x - 16</u>

6x³ -  4x² -   8x -16

\text{The product of the polynomials is $\large \boxed{\mathbf{6x^{3} - 4x^{2} - 8x -16}}$}
