Answer:

option b is correct,here is your explanation,

Step-by-step explanation:

2^(x+y)=2^(x-y)=2^3/2

√8=8^1/2=(2)³^1/2=2^3/2

if bases are same powers are equal

x+y=x-y=3/2

2y=0=3/2

y=0/2=3/2

y=3/2

Answer 2

Answer:

c) 0 is the answer.

Step-by-step explanation:

( x+y ) ( x-y )

As 2 = 2

This means ' y ' makes no difference in the value.

This clearly indicates that y = 0

( x+y ) ( x-y )

2 = 2

therefore

x + y = x - y

y = - y

2y = 0

y = 0
