1.) 2/9 (explanation: the square root squares both the denominator and the numerator if it is a perfect square)

2.) 2 (the fraction 0.8/0.2 simplifies to 4 which is them square rooted)

3.)0.6

4.)-7

5.) 11i (i stands for the square root of -1 since it is imaginary. Squares of numbers are imaginary when the number under the radical is negative since a real number squared can never be negative )
