Question

6 ( x⁴ y³x²- x³ y⁴z²+ x² y² y³) by 2xyz​

Answer 1

Answer:

30

Step-by-step explanation:

Given x + y + z = 10

(x + y + z) ² = 100

x ² + y ² + z ² + 2 (xy + xz + yz) = 100-

Now x ² + y ² + z ² = 38

implies xy + xz + yz = 31

or (xy + xz + yz) ² = (31) ²

using identity x ³ + y ³ + z ³ - 3xyz = (x + y + z) (x ² + y ² + z ²-xy -xz- yz)

= 10 × [38- 31]

= 70

Now x ³ + y ³ + z ³ = 160

or 160- 3xyz = 70

3xyz = 90

xyz = 30

Answer 2

Answer:

The subarctic is an area of the Northern Hemisphere that lies just south of the Arctic Circle. The taiga lies between the tundra to the north and temperate forests to the south. ... In Russia, the world's largest taiga stretches about 5,800 kilometers (3,600 miles), from the Pacific Ocean to the Ural Mountains.
