To find:

The value of the given expression.

Solution:

We have,

$(5^2)(7^2)(3^2)$

On simplification, we get

$(5^2)(7^2)(3^2)=(25)(49)(9)$

$(5^2)(7^2)(3^2)=11025$

Therefore, the value of the given expression is 11025.

Answers

Answer:

4 times

Step-by-step explanation:

Note,

60 seconds = 1 minute
120 seconds = 2 minutes (60*2).

Since the student rode a horse for 120 seconds, to find the number of times the student riding the carousel completed the up-down cycle, we divide it by 30 seconds (which is the duration for the horse to complete one up-down cycle) because the student would be having the same duration as the horse because he was on top the horse.

Hence, we have;

120/30 = 4
