2. [tex]\sqrt[n]{5}[/tex]
The expression [tex]x^{\frac{1}{2} }[/tex] is also known as [tex]\sqrt[]{x}[/tex], and the expression [tex]x^{\frac{2}{3} }[/tex] is also known as [tex]\sqrt[3]{x^{2} }[/tex]. In other words, the numerator of the exponent stays with the variable and the denominator of the exponent goes outside the square root sign.
3. 1/6
I just plugged this into my calculator. The equation for area is A = lw, so by plugging this into your calculator, you get .16666..., which is equal to 1/6
Hope this helps :)
