What is the power of (u) in (13u+9)?
Answer and explanation
Correct answer: 1
In \(13u+9\), the variable \(u\) can be written as \(u^1\), so its power is 1. The number 13 is the coefficient of \(u\), and 9 is the constant term; neither is the power. Hence, this is a linear polynomial in \(u\). Exam tip: When no exponent is written on a variable, its power is 1.
