Mathematics

Vlad [161]4 years ago
4 0
y^4-81x^4=y^4-(3x)^4=(y^2-(3x)^2)(y^2+(3x)^2)=(y-3x)(y+3x)(y^2+9x^2)

Depending on the field over which you're factoring, you may also write the last factor as

y^2+9x^2=(y-3ix)(y+3ix)

What is 10 - 4 and 2/3?
Ymorist [56]
10 - 4 2/3

First, we convert mixed fraction into improper fraction.

4 2/3 = ((4*3)+2)/3 = 14/3

In subtracting fractions:
1) Both must have the same denominator.
10 is 10/1 and 14/3 have different denominators. 

2) Once they have the same denominator, then subtraction may be performed.

10 - 14/3 = 10 * 3/3 - 14/3 = 30/3 - 14/3 = 16/3

3) 16/3 must be simplified.

16/3 = 5 1/3

10 - 4 2/3 = 5 1/3
