Simplify the expression using the power rule. \[ \left(x^{14}\right)^{7} \] \( \left(x^{14}\right)^{7}=\square \) (Type exponential notation with positive exponents.)

Using the power rule, which states that \((a^m)^n = a^{m \cdot n}\), we can simplify the expression \(\left(x^{14}\right)^{7}\) by multiplying the exponents: \[ \left(x^{14}\right)^{7} = x^{14 \cdot 7} = x^{98}. \] So, the simplified expression is \(x^{98}\). It's always fun to remember that the power rule is a fundamental part of working with exponents, making it easier to handle larger expressions without getting bogged down in complexity. Plus, mastering these rules can help you tackle higher-level math problems with confidence!
