Simplify: `(a xx b) xx (a^(-1) + b^(-1) )`
(a) `a - b`
(b) `a`
(c) `a + b`
(d) `b`

Simplify (x^(a+b)xx x^(b+c)xx x^(c+a))/((x^(b)xx x^(b)xx x^(c))^(2))

Find the value of ( a - b ) times ( a + b ) + ( b -c ) times ( b + c ) + ( c + a ) times ( c - a ) = A) -1 B) 0 C) 1

Simplify log(a^(2)times b^(3))-log((a^(3))/(b^(2)))

(a.(b xx c))/(b.(c xx a))+(b.(a x b))/(a. (b xx c)) is equal to
