3. Which of the following is

?*TRUE*$x\backslash \; \backslash frac\{1\}\{2\backslash \; \}\backslash cdot\backslash \; x\backslash \; \backslash frac\{1\}\{2\}=2x\backslash \; ^\{\backslash frac\{1\}\{2\}\}$

$x\backslash \; \backslash frac\{1\}\{2\backslash \; \}\backslash cdot\backslash \; x\backslash \; \backslash frac\{1\}\{2\}=x\backslash \; \backslash frac\{1\}\{4\}$

$x\backslash \; \backslash frac\{1\}\{2\}\backslash cdot\backslash \; x\backslash \; \backslash frac\{1\}\{2\}=x^2$

$x\backslash \; \backslash frac\{1\}\{2\}\backslash cdot\; x\backslash \; \backslash frac\{1\}\{2\}=x$
