Answer:
1. 11
2. 5.65685...~ 5.7
3. 4.2426...~ 4.2
4. .75
Step-by-step explanation:
1.) 11*11=121
2.) 5*5=25, 6*6=36
So the answer is between 5 and 6. It is closer to 6^2 than 5^2. I used a calculator to figure out the exact answer.
3.) 54/3=18, 4^2=16, 5^2=25
It is closer to 4^2 than 5^2. about 2/9 off (between the two answers). 4.242...
4.) 9/16= .5625. √.5625= .75
Hope this helps:) Have a good day!
