Question

For what integral values of x, 2raised to x x 5 raised to x ends in 5?
(C) no value of x A 0
(B) 1
(D) 2
It degree of both f(x) and (f(x) +g (x) is 18, then degree of g(x) must be
(A)> 18
(B) equal to 18
C less than equal to 18
(D) none of these
if the median of the data X1, X, X3, X, X5, X6, X. xs is 'a', then find the median of the data X3 X4, X.
X; Where (X) = X1 <X2<X3 < X4< X6 < x7<X8)
A a B a\2 C a\4
(D) can not say​

Answer 1

For No integral values of x, 2ˣ x 5ˣ ends in 5

Step-by-step explanation:

2ˣ * 5ˣ

= (2 * 5)ˣ

= 10ˣ

10ˣ will end with 1 for x = 0

and end with 0 for all other integral values

Hence for No integral Value of x  2ˣ * 5ˣ ends with 5

It degree of both f(x) and (f(x) +g (x) is 18, then degree of g(x) must be ≤ 18
