What is the value of \((35)^3\)?
Answer and explanation
Correct answer: 42875
The cube means multiplying the number three times. First compute the square: \(35^2=35\times35=1225\). Then \(35^3=1225\times35=(1225\times30)+(1225\times5)=36750+6125=42875\). Option C (42775) is only 100 less — a typical arithmetic slip when adding partial products. Thus the correct value is 42875. Exam tip: compute the square first and then multiply by the base number to reduce mistakes in multi-digit multiplication.
