dear Raunak,


the answer to your question is 2


we have x-2=22/3-21/3


then cubing both sides to get,


(x-2)3= 6(x-2)


thus expnding to get,


x3-6x2+6x=2

x=3^1/2,y=5^1/3 then (x+y)’s rationalise factor
 
 
First, make the powers equal x = 3 1/2 = 3 3/6 = 27 1/6 y = 5 1/2 = 5 2/6 = 25 1/6 x + y = 27 1/6 + 25 1/6 Now, rationalising factor is ( 27 1/6 - 25 1/6 ) ( 27 2/3 + 27 1/3 25 1/3 + 25 2/3...

Find the value of a for which the limit of function exists at x = 0. f(x) = (1-cos4x)/x 2 , x f(x) = a, x = 0 f(x) = (x) 1/2 /((16 + x 1/2 ) 1/2 – 4), x > 0
 
 
Ans: Since the limit of function exist at zero. So at x = 0 LHL = f(0) = RHL Apply L’Hospital rule
