Question

if x=5 and y=2 then find the value of (x^x + y^y )^-1​

Answer 1

Answer:

On substituting the value x = 5 and y = 2 in

(x × x + y × y ) × -1

( 5 × 5 + 2 × 2 ) × -1

( 25 + 4 ) × -1

(29) × -1

-29

Answer 2

Answer:

$\frac{1}{3129}=0.0003195$

Step-by-step explanation:

Given Expression :

                   $(x^x+y^y)^{-1}$

To find :

Value of the expression on x=5 and y=2.

Solution :

Substituting the value of x and y in the above expression we get

               =    $(5^5+2^2)^{-1}$

               =   $(3125+4)^{-1}$

               =   $\frac{1}{3129}$

               =   0.0003195

Hence the value of the Expression = 0.0003195 .
