The maxinum value M of `3^(x)+5^(x)-9^(x)+15^(x)-25^(x)`, as x varies

1.	The maxinum value M of `3^(x)+5^(x)-9^(x)+15^(x)-25^(x)`, as x varies over reals, satisfies-A. 3 lt M lt 5B. 0 lt M lt 2C. 9 lt M lt 25D. 5 lt M lt 9
Answer» Correct Answer - A::B `Mlea+b-ab` `Mlt1-(a-1)(b-1)" min is zero"` hence `0ltMlt2`
