In this case, you just multiply the expression under the root that gave the greatest integer (as you pull the square root of that number). See how I did: 4 multiplied by 31, which gives 124 then pull out the square root of 4, because 31 can not be, because it is a prime number and root would be an irrational number.
What digit(s) can be in the one's place of a number that has 5 as a factor?

ANSWER: 60
8.
Turn the whole number into a fraction by multiplying 3 by 8, also write an 8 under your answer, put the negative in front of the fraction
now we have -24 over 8 divided by 7 over 8
divide -24 by 7
now we have -3 over 8
