The value of √ ( l o g 2 0.5 4 ) is Options: A . &nbsp -2 B . &nbsp √ ( − 4 ) C . &nbsp 2 D . &nbsp None 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 $\sqrt{(l o g_{0.5}^{2} 4)}$ is

Options:

A . -2

B .

\sqrt{(- 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
