The box provides some examples of how exponents can be used to shorten repeated multiplication. The first, third, and fourth boxes all show how the repeated multiplication of 2, 3, and 5 can all be abbreviated as $2^4, 3^2$ and $5^3$ . The only expression which doesn't belong is $3+3+3+3=3(4)$ , because it's showing how repeated addition can be shortened to multiplication.
