What is the value of (18^2 \div 18^0)?
Advertisement
Answer and explanation
Correct answer: 324
Any non-zero number raised to the power 0 equals 1, so \(18^0=1\). Therefore, \(18^2 \div 18^0=324 \div 1=324\). Option 1 is only the value of \(18^0\), not of the complete expression. Exam tip: before applying the zero-exponent rule, check that the base is non-zero.
