Complex numbers are numbers of the a + bi where a and b are real number and i is the imaginary square root of -1.
7 root 5
There are infinitely many of them. They include square root of (4.41) square root of (4.42) square root of (4.43) square root of (4.44) square root of (4.45) square root of (5.3) square root of (5.762) square root of (6) square root of (6.1) square root of (6.2)
a + bi. a & b are both real numbers. the number i is the imaginary unit equal to the positive square root of -1.
245 245
√245 = √(49 x 5) = √49 x √5 = 7√5
Expressed as a surd in its simplest form, sqrt(245) is equal to 7 sqrt(5).
Imaginary number
Two of the integers are -2 and 5.
sqrt(245) = sqrt(49*5) = sqrt(49)*sqrt(5) = 7*sqrt(5)
The factor pairs of 245 are: 1 × 245 5 × 49 7 × 35
[ 0 + 7i ] and [ 0 - 7i ] is.
The standard form of a complex number is a+bi. So the standard form of the negative square root of 5i is 0-√(5i).
245 * 245 = 60025
A number of the form a+bi where a and b are real numbers and i is the square root of -1.
√80 - √245 = √(16*5) - √(49*5) = √16*√5 - √49*√5 = 4√5 - 7√5 = -3*√5
