For this case we must rewrite the expression given by:

\sqrt [n] {x ^ m}

By definition of power and root properties we have to:

\sqrt {a} = a ^ {\frac {1} {2}}

Then, the given expression can be rewritten as:

\sqrt [n] {x ^ m} = x ^ {\frac {m} {n}}

Answer:

\sqrt [n] {x ^ m} = x ^ {\frac {m} {n}}

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30​
Natasha_Volkova [10]

Answer:

P(2)=0 then x-2 is a factor of P(x)

Step-by-step explanation:

To see if (x-2) is a factor just plug in 2 for x into the polynomial expression.

2(2)^3-3(2)^2-17(2)+30

2(8)-3(4)-34+30

16-12-34+30

4-34+30

-30+30

0

Since P(2)=0 then x-2 is a factor

\cfrac{21}{3}\cdot x^2x^{-1}y^6y^{-1}+\cfrac{6}{3}\cdot x^1x^{-1}y^3y^{-1}-\cfrac{30}{3}\cdot x^1x^{-1}y^1y^{-1}

Kaitlyn is making a quilt she purchased a 46 foot long piece of lace to sew around the edges of the quilt she needs 322 inches o
kupik [55]

Answer:

<u>19.17 feet</u> of lace will be leftover.

Step-by-step explanation:

Given:

Kaitlyn is making a quilt she purchased a 46 feet long piece of lace to sew around the edges of the quilt she needs 322 inches of lace for the quilt.

Now, to find the feet of lace will be leftover.

<u><em>Total feet of lace =</em></u> <u>46</u>.

Kaitlyn needs lace for the quilt = 322 inches.

So, by using conversion factor we change inches into feet:

12 inches = 1 foot.

322 inches = \frac{322}{12} =26.83\ feet.

<u><em>Feet of lace she need for the quilt =</em></u> <u>26.83</u>.

Now, to get the feet of leftover lace:

<u><em>Total feet of lace - feet of lace she need for the quilt</em></u>

=46-26.83

=19.17\ feet.

Therefore, 19.17 feet of lace will be leftover.
