Question

find the value of x if logx base 8 equal to 2.5 and logy base 2 equal to 6​

Answer 1

Answer:

log (base 2)x+log (base 2)y>=6

=> log (base 2)xy >=6

[Express 6 as log (base 2) ; 6=log(base 2)2^6.]

Now log (base 2)xy > =log (base 2)2^6

Or log (base 2)xy > = log (base 2)64

Or xy > = 64

Or x= >64/y or x=64/y □ ANSWER.

[ HERE y is Positive Real Number & Not equal to ZERO ]
