Question

In a cafeteria, five groups of five friends ordered pizza, one for each. How many pizzas have been ordered?

• A. ${10}^5$
• B. $5^2$
• C. 10 $\times$ $1^5$
• D. $5^5$

Answer 1

The correct option is B $5^2$

Five groups of five friends ordered pizza, one for each.

Hence, the total pizza ordered = 5 $\times$ 5

This is equivalent to 5${}^2$.

Hence, the number of pizza that have been ordered = 5${}^2$
