confused with these two
simplify 13 a/2 * 13 1/2
also
2 1/3* 4 1/3

13 a/2 * 13 1/2
= (13/2)(27/2) a
= 351 a/4
7/3 * 13/3 = 91/9 
for 13 1/2 * 13 1/2 in my multiple choice it says the options are a) 13 b) 13 1/4 c) 1 or d 13 with the real number root
for 2 1/3 * 4 1/3
the options are a) 2 b) 4 c) 3 real number root 2 or d) real root 2 
the real number root is on the graphing calculator if u press 2nd and x2 if what im saying is confusing

Hey, please use notation ^ for power.
13^(1/2) * 13^(1/2) = 13 ^1 = 13
2^(1/3) * 4^(1/3)
= 2^(1/3) * 2^(2/3)
= 2^1
= 2
