Find the Domain (3ab)(-5ab)

Problem

(3*a*b)*(−5*a*b)

Solution

1. Identify the type of expression provided. The expression (3*a*b)*(−5*a*b) is a polynomial expression in terms of the variables a and b

2. Recall the definition of a domain for polynomial functions. Polynomials are defined for all real numbers because there are no denominators that could be zero and no even roots of negative numbers.

3. Determine the constraints on the variables. Since there are no restrictions such as division by zero or logarithms of non-positive numbers, the variables a and b can take any real value.

4. State the domain in terms of the set of all real numbers for both variables.

Final Answer

Domain: *{(a,b)|a∈ℝ,b∈ℝ}
