Question

plzzz solve these two questions fast

Answer 1

HEY MATE

KEEP ASKING QUESTIONS

A1

LET US TALK OF THE NUMERATOR

2N+2(N-1)

=2N(1+1/2)

=2N(3/2)

FOR THE DENOMINATOR

2N+1-2N

=2N(2-1)

=2N

NOW

$\frac{numeratotr}{denominator}$

=2N(3/2)/2N

=3/2

=LHS

HENCE PROVED

A2

HERE

(X, Y) =(Y, X)

LET US THHINK THAT THE FIRST ONE IS 1,2 AND THE SECOND ONE IS 2,1

BUT WE GET DIFFERENT POINTS

SO THIS CAN ONLY BE POSSIBLE WHEN X=Y

SO HERE

9(Y-X)

=9(X-X)

=9(0)

=0
