Expert Answer

4^x = 6^y = 9^z = k

4^x = k

log 4^x = log k

x = log k/log 4 similarly y = log k/log 6 and z = log k/log 9

1/x + 1/z = log 4/log k + log 9/log k

= log 36/log k

= log 36/ log 6^y

= log 6²/log 6^y

= 2log 6/y log 6

= 2/y

Q) Find the range of f(x) = x + 1/x Ans) See the image which I have uploaded.. I have just broken the eqn into √x² + 1/√x² +2 -2 ..and have formed the identity (a+b)² and the range is coming (-∞, 2 ] U [ -2, ∞ ) which is wrong.. the correct range is coming from (a-b)² which is (-∞, -2 ] U [ 2, ∞ ). My Doubt- Why (a+b)² is not giving the correct range? Request- Please send the solution using (a+b)². I've attached an image and let me know if I'm wrong somewhere or why the correct solution isn't coming by using (a+b)². Thanks, Samit Future Top 50 ranker in JEE ADVANCE
