4.(x-y)power3=xpower3 +ypower3=_______+_______
5.​​

Answer 1

Answer:

1.√7-√6/7

2. 2

3. 8/15

4.x³-y³

Step-by-step explanation:

1.

1/√7 - √6

To rationalise

1/√7×√7/√7

√7/7

Now sub. √7/7-√6

LCM= 7

√7-√6/7

2.

Degree of polynomial 4y² = 2

As the highest power is 2

3.

2²/3 × 2/5

4/3× 2/5

= 8/15

4.

(x-y) ³ ( x³-y³)

(x³+y³) (x³-y³)

(a+b) (a-b)

= x³-y³
