Let x=3 1/3 =13/4
And y=4 1/3 = 13/3
Now let the given number
Z= { (x4 –y4) / (x²-y²) }
={ (x²-y²) (x²+y²) / (x²-y²) }
Z=(x²+y²)
Now putting values of x and y
Z= (13/4)² + (13/3)²
=169/16+169/9
=169 ( 1/16+1/9)
=169(9+16)/144
Z=169*25/144
Thus the square root of Z
=√( 169*25/144)
=13*5/12
=65/12
= 5 5/12
Answer (c) 5 5/12
