The value of √(log20.5 4) is
1) -2
2) -4 (in root)
3) 2
4) None of these
Hi Vishrant,
The value of √ should always be positive √(x2) =|x|
Therefore the answer is 2
hi Vishant
you should remember that √(a2)=|a|
so √(log20.5 4)=|log0.5 4|
=|log2-1 22|
=|-2 log22|
=2 log22
=2 { sinse we know logaa=1}
so option 3 is correct
