1.(√5)^5 = 2.(3 2/3 ) ^ 3/5

1. [tex] \sqrt{a}* \sqrt{a} =a[/tex]
[tex] \sqrt{5}* \sqrt{5}* \sqrt{5}* \sqrt{5}* \sqrt{5}
= 5 * 5 * \sqrt{5}
= 25\sqrt{5}[/tex]

2. [tex]a \frac{b}{c} = \frac{a*c+b}{c} [/tex]
[tex]3 \frac{2}{3} * \frac{3}{5} [/tex]
= [tex] \frac{11}{3} * \frac{3}{5} [/tex]
= [tex] \frac{11}{5} [/tex]
