Students Messaging Progression: At $11$ : $00$ AM, each of the $25$ students sent the message to $5$ more students. So, $25$ students $\times 5 = 125$ students got the message at $11$ : $00$ AM.
Noon Message Recipients: If the pattern continues, at noon, each of the $125$ students will send the message to $5$ more students. So, $125$ students $\times 5 = 625$ students will get the message at noon.
Exponential Calculation: Calculating the correct value of $2^{5}$ : $2 \times 2 = 4$ , $4 \times 2 = 8$ , $8 \times 2 = 16$ , $16 \times 2 = 32$ . So, $2^{5} = 32$ .
