Which of the numbers \(7^2, 4^3, 3^4, 6^3\) is the greatest?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → \(6^3\)
The powers have different bases and exponents, so the quickest way to compare them is to work out each value.
Option (1) gives \(7^2=49\)
Option (2) gives \(4^3=64\)
Option (3) gives \(3^4=81\)
Option (4) gives \(6^3=216\), by far the greatest
