The solution set of the equation `x^(log_x(1-x)^2)=9` isA. `{-2,4}`B.

1.	The solution set of the equation `x^(log_x(1-x)^2)=9` isA. `{-2,4}`B. {4}C. `{0,-2,-4}`D. none of these
Answer» Correct Answer - B `x^(log_(x)(1-x)^(2))=9` `rArr (1-x^(2)=9` `rArr 1-x= pm 3` `rArr x=-2, 4` But x = -2 is not possible `rArr x = 4`

If `a gt 1, x gt 0` and `2^(log_(a)(2x))=5^(log_(a)(5x))`, then x is equal toA. `(1)/(10)`B. `(1)/(5)`C. `(1)/(2)`D. 1
If `x_(1)` and `x_(2)` are solution of the equation `log_(5)(log_(64)|x|+(25)^(x)-(1)/(2))=2x`, thenA. `x_(1)=2x_(2)`B. `x_(1)+x_(2)=0`C. `x_(1)=3x_(2)`D. `x_(1)x_(2)=64`
