How to factor 9x^4-6x^2y^4+y^89x4−6x2y4+y8

Mathematics

Virty [35]3 years ago

Answer:

(3x^2-y^4)(3x^2-y^4)

Step-by-step explanation:

We'll assume the correct expression to be factored is

9x^4-6x^2y^4+y^8

One must try to find out if the expression is a perfect square. To test it, we'll take the square root of the first and the last term. If they are exact, we'll procceed with the next step

\sqrt{9x^4}=3x^2

\sqrt{y^8}=y^4

Since both are exact, we'll test if the middle term is twice the product of both square roots:

2(3x^2)(y^4)=6x^2y^4

We confirm the middle term equals the above expression. All tests confirm the original expression is

\left ( 3x^2-y^4 \right )^2

The required factoring is

(3x^2-y^4)(3x^2-y^4)

Use​ Gauss's approach to find the following sums​ (do not use​ formulas). 1+3+5+7+...999
muminat
S=1+3+5+\cdots+995+997+999
S=999+997+995+\cdots+5+3+1
\implies 2S=(1+999)+(3+997)+(5+995)+\cdots+(995+5)+(997+3)+(999+1)

2S=\underbrace{1000+1000+\cdots+1000+1000}_{500\text{ times}}

(We are adding 500 instances of 1000 because that's how many odd numbers there are between 1 and 1000, inclusive.)

2S=500\times1000=500000
\implies S=250000

On a shelf at a gaming store, there are five Sony Playstations and three Nintendo Wii consoles left. If one gaming system is sel
Tpy6a [65]

Step-by-step explanation:

a probability is always desired cases over total possible cases.

so, we have actually 8 systems (5 + 3) we can pick from.

therefore, the total possible cases are 8.

the desired case is in this question to pick one of the 3 Wii consoles.

the probability to pick a Wii is therefore

3/8 = 0.375
