Answer:
168
Step-by-step explanation:
I just calculate it by a calculator
but really using your brain... is like: devide 28224 by the smallest squre number which is 4 equals to 7056, and continue deviding this number by 4 which is 1764...
the processes are:
28224÷4=7056
7056÷4=1764
1764÷4=441
441 cannot be devided by 4, if u r familiar with the number 121, 144 which are 11^2 and 12^2, then you can figure 441 is actually 21^2. Then the answer will be √28224=√4*4*4*441=√4*√4*√4*√441=2*2*2*21=168
