Question

Solve this please!! Please help

Answer 1

Hey!!!!....here is ur answer

Sin^-1x+sin^-1y+sin^-1z=3pi/2

as we know that the maximum value of sun^-1x is pi/2

so if Sin^-1x+sin^-1y+sin^-1z=3pi/2 then..

sin^-1x=sin^-1y=sin^-1z=pi/2

so the value of x=y=z=1

Now... f (1)=2

f (x+y)=f (x) f (y)

f (1+1)=f (1) f (1)

f (2)=4

similarly... f (2+1)=f (2) f (1)

f (3)=8

Now putting all the values in...

x^f (1)+y^f (2)+z^f (3)-x+y+z/x^f (1)+y^f (2)+z^f (3)

=1^2+1^4+1^8-1+1+1/1^2+1^4+1^8

=1+1+1-3/1+1+1

=3-3/3

=3-1

=2

so the C option is the correct option

Hope it will help you ☺
