Answer 1

Answer:

8

Step-by-step explanation:

(x/y)^x-y = (2/4)^2-4

              => (1/2)^-2 = 4

(y/x)^y-x = (4/2)^4-2

              => 2^2 = 4

4+4 = 8

Answer 2

$( \frac{x}{y} ) { }^{x - y} + ( \frac{y}{x} ) {}^{y - x}$

After adding the value

$( \frac{2}{4} ) {}^{2 - 4} + ( \frac{4}{2} ) {}^{4 - 2}$

$( \frac{2}{4} ){}^{ - 2} + ( \frac{4}{2} ) {}^{2}$

$( \frac{4}{2} ) {}^{2} + ( \frac{4}{2} ) {}^{2}$

$( \frac{4}{2} ) {}^{4}$

$\frac {256}{16}$

$16$
