3y=ab. Divide by 3 to get y=ab/3

3

(a x b)^b

=ab x b^2

=ab^3

1. ab x ac = ab+c

Example: 2 x 22 = 21+2 = 23

2. ab ÷ ac = ab-c

Examples:

35 ÷ 32 = 35-2 = 33

32 ÷ 35 = 32-5 = 3-3

3. a-b = 1/ab

Example: 3-3 = 1/33

b*ab = ab2

Suppose b*ab = ab + b2. Assume a and b are non-zero integers. Then

ab2 = ab + b2

b = 1 + b/a would have to be true for all b.

Counter-example:

b = 2; a = 3

b(ab) = 2(3)(2) = 12 = ab2 = (4)(3)

ab + b2 = (2)(3) + (2) = 10

but 10 does not = 12. Contradiction. So it cannot be the case that b = 1 + b/a is true for all b and, therefore, b*ab does not = ab + b2
