What is the value of (5^1\times5^2)?
Answer and explanation
Correct answer: 125
When powers with the same base are multiplied, their exponents are added: \(5^1\times 5^2=5^{1+2}=5^3=125\). Therefore, the correct answer is 125. The value 25 is only \(5^2\), so it is not correct here. Exam tip: add exponents when multiplying like bases and subtract them when dividing.
