Step-by-step explanation:

${x}^{y} + {y}^{x } \\ \\ {( - 1)}^{2} + {2}^{ (- 1)} \\ \\ 1 + \frac{1}{2\:^1} \\ \\ 1 + \frac{1}{2} \\ \\ \frac{2 + 1}{2} \\ \\ \frac{3}{2}$

Answer 2

Answer:

1.5

Step-by-step explanation:

x power y,

x^y

y power x,

y^x

Given,

x = - 1

y = 2

To find : x^y + y^x = ?

x^y

= ( - 1 )^2

= ( - 1 ) ( - 1 )

= 1

y^x

= 2^( - 1 )

= 1 / ( 2 )^1

= 1 / 2

= 0.5

x^y + y^x

= 1 + 0.5

= 1.5
