The simplification of a rational multiplication or division problem is given. each step is numbered under the problem in parenthesis - (1), (2), (3), and (4). identify the number of the first step where a mistake occurs, if there are any.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
