What is the power of (y) in the expression (2x^2y^3)?
Answer and explanation
Correct answer: 3
In \(2x^2y^3\), the factor containing \(y\) is \(y^3\), so the power of \(y\) is 3. The power of \(x\) is 2, and their sum, 5, gives the total degree of the term, not the power of \(y\). Exam tip: To find the power of a variable, look at the exponent written directly on that variable.
