Question

please give me answers of these questions ​

Answer 1

Answer:

(i) (a+b)+c = a+(b+c)

Or, {3/4+(-1/2)}+1/2 = 3/4+{(-1/2)+1/2}

Or, {3/4-1/2}+1/2 = 3/4+{0}

Or, {3/4-2/4} + 1/2 = 3/4

Or, 1/4+1/2 = 3/4

Or, 1/4+2/4= 3/4

Or, 3/4 = 3/4

Or, LHS = RHS

hence, verified.

(ii) x(y+x) = xy+xz

Or, 1/2(1/3+1/4) = 1/2×1/3+1/2×1/4

Or, 1/2(4/12+3/12) = 1/6+1/8

Or, 1/2×7/12 = 4/24+3/24

Or, 7/24 = 7/24

Or, LHS= RHS

hence, verified.

(iii) p+q = q+p

Or,-3/2+4/5 = 4/5+(-3/2)

Or, -15/10+8/10 = 8/10-15/10

Or, -7/10 = 17/10

Or, LHS = RHS

hence, verified

ans,
