That depends on where the parentheses are in the question.
The square root of [ 27 - sqrt(12) ] is 4.8514 . (rounded)
sqrt(27) - sqrt(12) = 1.7321 . (rounded)
To get somewhat fancier about it . . .
sqrt(27) = 3 sqrt(3)
sqrt(12) = 2 sqrt(3)
sqrt(27) - sqrt(12) = sqrt(3) times (3 - 2) = 1 sqrt(3) = 1.732 (rounded)
The numbers are: 6 plus square root of 27 and 6 minus square root of 27
The numbers are: (-12+square root of 171) and (-12-square root of 171)
square root of 27 plus the square root of 75
So I assume you mean the square root and square root of 27=square root of (9x3)=3(square root (3))
The square root of 27 is 9 root 3.
The numbers are: 6 plus square root of 27 and 6 minus square root of 27
27i where i is the square root of -1.
The numbers are: (-12+square root of 171) and (-12-square root of 171)
The square root of 27 plus the square root of 5 = 7.4322204
square root of 27 plus the square root of 75
The square root of 27 is 5.196152423...The square root of 27 is 5.19615242.5.19615242 x 5.19615242 = 27Simplified, the square root of 27 is 3 times the square root of 3.6.256 6.256
square root(27) = 5.19615242
-27 does not have a square root. The mathematical expression for the square root of-1 is i.
29
So I assume you mean the square root and square root of 27=square root of (9x3)=3(square root (3))
The square root of 27 is 9 root 3.
√(27 + 75 + 12) = √ 114 = 10.68 rounded
