What does log^2_a b mean??

The question is :Find the value of  (log²_0.54)^0.5..

Ans is 2..

Pl explain soon..

Rates assured!

Thanks!!

the ans is -2 .. isnt it ??

c do it like this

1. there is a square on log function and then its under root so the question simplifies to log 4 to the base 0.5

2. invert the base and put a negative sign in front of the function

3. solve it

Even I got -2...the answer is +2..so I thought there must be some fundamental mistake in my understanding..

I solved it the same way as you..

well i think the ans must b -2 only... and i m preety sure abt it

0.5=1/2

log_o.5⁴⁼ -2

use this

well ya...we r using this only but the ans could be -2 or +2 na... just put the value
