Answer:

8\sqrt[3]{(5)}

Step-by-step explanation:

We have been given an expression (8\times 320)^{\frac{1}{3}. We are asked to find which expression of given expressions is equal to our given expression.

Using exponent property (a)^{\frac{m}{n}}=\sqrt[n]{a^m} we can rewrite our given expression as:

\sqrt[3]{(8\times 320)^1}

\sqrt[3]{(8\times 320)}

Rewriting 320 as 64\times 5 in our given expression we will get,

\sqrt[3]{(8\times 64\times 5)}

\sqrt[3]{(2^3\times 4^3\times 5)}

Pulling our 2 and 4 from cube root we will get,

2\times 4\sqrt[3]{(5)}

8\sqrt[3]{(5)}

Therefore, the expression 8\sqrt[3]{(5)} is equal to our given expression and option D is the correct choice.

(8 x 320)^1/3

(2560)^1/3

(64*40)^1/3

64^1/3   *40^1/3

4 * (8^1/3) * 5^1/3

4 * 2 * 5^1/3

8 *5^1/3

None of your choices are written correctly

Answer:

2

Step-by-step explanation:

Given:

-2(1-4x)=3x+8

Let's distribute the parenthesis

-2+8x=3x+8

Let's subtract -3x from both sides

-2+5x=8

Let's add 2 to both sides

5x=10

Now, let's divide both sides by 5 to get x alone

x=2

Hope this is helpful

Based on the polynomial reminder theorem, what is the value of the function when x= -5
densk [106]

Answer:

-15

Step-by-step explanation:

Given is a polynomial in x

F (x)= x^4 + 12x^3 + 30x^2 - 12x + 70

We have to find the remainder when the above polynomial is divided by x+5

Remainder theorem says that f(x) gives remainder R when divided by polynomial x-a means f(a) = R

Applying the above theorem we can say that value of the function when x =-5

= Remainder when f is divided by x+5

= F(-5)

Substitute the value of -5 in place of x

= (-5)^4 + 12(-5)^3 + 30(-5)^2 - 12(-5) + 70

= 625-1500+750+60+70

= 5

Hence answer is 5
