In the equation ab = c, solve for c.

• A. ab
• B. a+b
• C. a-b
• D. a/b

Answer: (A)

Solving for c means express c in terms of the other variables. The equation ab = c already states that c is the product of a and b, so the correct form is c = ab. This matches the given relationship exactly.

The other expressions would describe different relationships: a + b would be the sum, a − b the difference, and a/b the quotient. Since the equation specifies c as the product ab, only c = ab is correct.
