If x > 0, what is the value of x5?
(1) ~$\sqrt{x}$~= 32
(2)~$x^2 = 2^{20}$~
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
题目分析：
（1）若~$\sqrt{x}=32$~，则~$x=32^2$~，那么~$x^5=(32^2)^5$~
（2） 若~$x^2=2^{10}$~，则~$x=2^{10}$~，那么~$x^5=(2^{10})^5$~
因此，本题答案为（D），任何一个条件均能说明问题。
题目的大前提不能丢。。。。x>0
