Find the product.<br> a 4(3a2 - 2a + 1)<br><br> (typed answers not selection)
Rus_ich [418]

Answer:

3a^6-2a^5+a^4

Step-by-step explanation:

Use the rules of indices to find the product.

One of the rules is that when we multiply indices that have the same base we add the powers. For example:

x^4 * x^5 = x^9

So to work out a^4(3a^2-2a+1) we need to follow this rule.

Let's expand the bracket:

a^4(3a^2-2a+1) = (a^4)(3a^2)+(a^4)(-2a)+(a^4)(1)

Let's simplify keeping in mind the rule we know.

(a^4)(3a^2)=3a^6

(a^4)(-2a) = -2a^5 - remember that a = a^1

(a^4)(1) = a^4

Calculate the largest rectangular area one can enclose with 14 inches of string?
bagirrra123 [75]

The correct answer to this question is <span>12.25 sq inches.
</span>

The largest rectangle is a square.

So if you divide 14" by 4 then you get 4 3.5" sides.


Area of a rectangle = L*W

<span>Area of a rectangle = 3.5 * 3.5</span>

<span>Area of a rectagle = 12.25 sq inches</span>

Please solve this question?​
Alchen [17]

Given,

\lim_{x}^{a}\dfrac{x^{2/3}-a^{2/3}}{x-a}

We can use L'Hopital's Rule to get,

\lim_{x}^{a}\dfrac{2}{3-\sqrt[3]{x}}

Now plug in a,

\boxed{\dfrac{2}{3-\sqrt[3]{a}}}

Hope this helps.
