The value of √ ( l o g 2 0.5 4 ) is Options: A . &nbsp-2 B . &nbsp√(−4) C . &nbsp2 D . &nbspNone of these

Answer: Option C : C √ ( l o g 2 0.5 4 ) = √ { l o g 0.5 ( 0.5 ) − 2 } 2 = √ ( − 2 ) 2 = 2

The value of √(log20.5 4) is

Question

The value of

\sqrt{(l o g_{0.5}^{2} 4)}

Options:

A . -2

B . √(−4)

C . 2

D . None of these

Answer: Option C
:
C

\sqrt{(l o g_{0.5}^{2} 4)} = \sqrt{{l o g_{0.5} (0.5)^{- 2}}^{2}} = \sqrt{(- 2)^{2}} = 2
