What base corresponds to the exponent 2 in the expression \( x^{4} v^{2} ? \) The base that corresponds to the exponent 2 is

the variable \( v \). In the expression \( x^{4} v^{2} \), the exponent 2 is attached directly to \( v \), indicating that \( v \) is raised to the second power. So, whenever you see a variable with an exponent, that variable is your base for that particular exponent! Another point to consider is that exponents have some funky rules! For instance, when multiplying two terms with the same base, you add the exponents together. So, if you were to multiply \( v^{2} \) by \( v^{3} \), you would get \( v^{5} \) because \( 2 + 3 = 5\). Keep these rules in mind for quick calculations!
