Question

How many numbers can be entered in a 10 $\times$ 10 number grid, one at each? Express the answer in exponent form.

• A. ${10}^2$
• B. $2^{10}$
• C. ${10}^3$
• D. ${10}^{10}$

Answer 1

The correct option is A ${10}^2$

Total number of cells in 10 $\times$ 10 grid = 10 $\times$ 10

= 100

= ${10}^2$

Total number of cells in exponent form = ${10}^2$

Hence, ${10}^2$ numbers can be entered in a 10 $\times$ 10 grid.
