The square root of negative 121 is 11i which is the correct answer would be option (B).
A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib, where a, and b are real numbers and i is an imaginary number.
To determine the square root of negative 121
Let the square root of negative 121 is z
z² = -121
z = √(-121)
z = √(121)i
∵ i² = - 1 or i = √-1
Here i is an imaginary number.
z = √(11×11)i
z = 11i
Hence, the square root of negative 121 is 11i.
