Question

verify that a÷(b+c(#(a÷b)+(a÷c) for each of the given valuesof a,b and c .

(i) a=20, b=-2 c=4
(ii) a=-8,b=-1,c=2​

Answer 1

1. condition given

a÷ (b+c) ≠(a÷b) + (a÷c)

20 ÷ (-2+4) ≠ (20÷ -2) +( 20÷4)

20 ÷ 2 ≠ -10 +5

10 ≠ -5

2. condition given

a÷ (b+c) ≠(a÷b) + (a÷c)

-8 ÷ (-1+2) ≠ ( -8÷ -1) + (-8÷ 2)

-8 ÷ 1 ≠ 8 + (-4)

-8 ≠ 4
