Question 201267
Note: 
*[Tex \LARGE \left(x\right)^{\frac{m}{n}}=\sqrt[n]{x^m}]



In this case, the exponent of {{{1/2}}} means that you are taking the square root of everything in the parenthesis.



# 1


*[Tex \LARGE \left(\frac{4}{9}\right)^{\frac{1}{2}}=\sqrt{\frac{4}{9}}=\frac{\sqrt{4}}{\sqrt{9}}=\frac{2}{3}]



So *[Tex \LARGE \left(\frac{4}{9}\right)^{\frac{1}{2}}=\frac{2}{3}]



-----------------------

# 2

*[Tex \LARGE \left(\frac{9}{16}\right)^{\frac{1}{2}}=\sqrt{\frac{9}{16}}=\frac{\sqrt{9}}{\sqrt{16}}=\frac{3}{4}]



So *[Tex \LARGE \left(\frac{9}{16}\right)^{\frac{1}{2}}=\frac{3}{4}]
