Question

please help me.........​

Answer 1

Answer: 6÷x½+15÷y½=5

6*y½+15*x½÷(xy) ½=5

(6*y½+15*x½)²=(5(xy)½)²

36y+225x+180(xy)½=25xy......(1)

21÷x½-10÷y½=5

21*y½-10x½÷(xy) ½=5

(21*y½-10x½)²=(5(xy)½)²

441y+100x-420(xy)½=25xy....(2)

from 2 equations,

36y+225x+180(xy)½=441y+100x-420(xy)½

(6*y½+15*x½)²=(21*y½-10*x½)²

15y½-25x½=0

15y½=25x½

3y½=5x½

y=25x÷9

from equation (1)-

6(5x½÷3)+15x½=5(x5x½÷3)

25x½=25xx½÷3

x=3,from equation, 36y+225x+180(xy)½=441y+100x-420(xy)½

6y½+15x½=21y½-10x½

15y½=25*3½

y=75÷9=25÷3

x=3,y=25÷3
