4x-8x = -4x

√-4x stands. However, x could not possibly be a positive number, because:

(Negative) X (Positive) = (Negative) The square root of a negative number

is undefined-so...

(√-4x) + 9 Is your answer.

The answer is 0.

sqrt(4) = 2 sqrt(9) = 3 Therefore, the square root of 4 plus the square root of 9 is equal to 2 + 3 = 5.

3+14 = 17

The square root of 9 is 3, therefore 3 + 7 = 10

square root of 81 is 9...and plus 32 is 41.so the answer is 41
