The question is ambiguous because it is not clear where the parentheses end.
-5(sqrt(64)) - 3 = 5*(±8) - 3 =±
40 - 3 = -43 or +37
Just take the square root, and put a minus sign in front of it.
The answer is 2i. When dealing with negative square roots, the expression i is used to represent the square root of -1.
A negative number that is not an integer, of course. Examples are minus 1.5, minus pi, minus square root of 2, etc.
x = (-b plus_minus root(b2 - 4ac)) / 2aWhere plus_minus is the "plus or minus" sign, and "root" stands for the square root.
The square root of negative one is an imaginary number, signified by the italic lower-case i.
Negative square root is -√Square root of negative one is i.
There is no real answer. The square root of negative one is denoted i for imaginary.
Just take the square root, and put a minus sign in front of it.
It depends on whether you take the positive square root of 4 (YES) or the negative square root of 4 (No).
I, the square root of -1
The answer is 2i. When dealing with negative square roots, the expression i is used to represent the square root of -1.
The square root of -6400 is not a real number because the square root of a negative number is not defined in the real number system.
A negative number that is not an integer, of course. Examples are minus 1.5, minus pi, minus square root of 2, etc.
x = (-b plus_minus root(b2 - 4ac)) / 2aWhere plus_minus is the "plus or minus" sign, and "root" stands for the square root.
square roots of a negative number are imaginary, where i = square root (-1) sqrt (-2500) = sqrt (2500) i = 50 i
The square root of negative one is an imaginary number, signified by the italic lower-case i.
No, nor is it a real number. The square root of minus 54 is equal to the square root of plus 45, times i.
