Answer 1

Answer:

draw c by z in theatre maths it take alot time

Answer 2

Step-by-step explanation:

We have,

a

x−1 =bcaa x

=abca x =abc

a=(abc)

1/x …(1)

Similarly,

b=(abc)

1/y …(2)c=(abc) 1/z …(3)

Multiply (1),(2),(3)

abc=(abc)

1/x .(abc) 1/y .(abc) 1/z

abc=(abc) 1/x+1/y+1/z

∴ x1 + y1 + z1

=1xyzxy+yz+zx =1xy+yz+zx=xyz

xy+yz+zx−xyz=0
