Answer:
in exp
Explanation:
A. 3^1/2 * 3^1/2 = 3, which is congruent to 9^1/2, which is also 3.
B. 27=3^3, hence we can rewrite this as 3^3/6, or 3^1/2, which is NOT 3.
C. 27=3^3, so the first part of the expression can be written as 3^3/3 * 3^1/2, which is 3*3^1/2, which is 3^3/2, clearly not 3.
D. 81^1/2 is 9, and 9*9 is obviously not 3.
Thus, the only one that is equal to 9^1/2 is A.
