Answer:

x^3*y^4

Explanation:

The two denominators shown are x^3*y and x*y^4. The LCD must involve the largest power of x, which is x^3, and the largest power of y, which is y^4. Thus, the LCD is x^3*y^4.

Answer: x^3y^4 is the lowest common denominator.

Step-by-step explanation: To get both expressions to have a common denominator, multiply both of them to get them equal. For the first expression, multiply the numerator and denominator by y^3: 3y^3/x^3y^4

The second expression should be multiplied by the numerator and denominator by x^2: 7x^2/x^3y^4

(Add exponents when multiplying them) Now both expressions have common denominators.
