Explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  1/a^b = a^-b

__

  5\times2^{n-1}=5\times(2^n)(2^{-1})=5\times2^n\times\dfrac{1}{2}=\boxed{\dfrac{5}{2}\times2^n}

Solve using long division.
Mkey [24]

Answer:

Quotient is 3x-5 and remainder is 0.

Step-by-step explanation:

Given:

Dividend = 3x^2+7x-20

Divisor = x+4

The long division is shown in the attachment.

Step 1: we need to divide 3x^2+7x-20 with x+4 we first multiply x+4 with 3x we get the remainder as -5x-20

Quotient as 3x.

Step 2: Now the dividend is -5x-20 and divisor x+4 now we will multiply x+4 with -5 we get the remainder as 0 and Quotient as 3x-5

Hence Quotient is 3x-5 and remainder is 0.

Form a polynomial with zeros:−2 multiplicity 3; 1 multiplicity 2; 3 multiplicity 1;degree 6 You may leave your answer in factore
Darina [25.2K]

Answer:

f(x) = (x+2) (x+2)^3 (x-1) (x-6)

Step-by-step explanation:

The first zero, -2, corresponds to the factor x+2 of the polynomial.

Given that this zero, -2, has multiplicity 3, (x+2)^3 represent the first three factors of the polynomial.

The next factor stems from the zero 1:  (x-1).

The next 6 factors stem from the zero 6:  (x-6).

Writing the polynomial in factored form, we get:

f(x) = (x+2) (x+2)^3 (x-1) (x-6)
