54-7✓6

Answer 2

(1) 8 root 12 + 3 root 27

=> 8 root 3*2*2 + 3 root 3*3*3

=> 8*2 root 3 + 3*3 root 3

=> 16 root 3 + 9 root 3

=> 25 root 3

(2) Let x = 0.002 bar --------------------------(1)

=> 1000x = 2.2 bar

=> 1000x = 2.22 + 0.002

=> 1000x = 2.22 + x -----------------------(from 1)

=> 1000x - x = 2.22

=> 999x = 2.22

=> x = 2.22/999

Where, p = 2.22 and q = 999 and also q is not equal to zero.
