Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.
It is a pure imaginary number.Since (a+bi)-(a-bi) = 2bi, it is a pure imaginary number (it has no real component).
No, but √-23 is. An imaginary number is the square root of a negative number.
No. A complex number is a number that has both a real part and an imaginary part. Technically, a pure imaginary number ... which has no real part ... is not a complex number.
No, it is an imaginary number which is a complex number.
Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.
If a number is pure imaginary then it has no real component. If it is a real number, then there is no imaginary component. If it has both real and imaginary components, then it is a complex number.
an imaginary number is imaginary so no (i guess) this answer kind of sucks
-125 is NOT an imaginary number.
That quotient would be an imaginary number. The actual number depends on exactly what imaginary number you divide the 7 by.
It is a pure imaginary number.Since (a+bi)-(a-bi) = 2bi, it is a pure imaginary number (it has no real component).
No, but √-23 is. An imaginary number is the square root of a negative number.
An imaginary number is a number that has the square root of -1 as one of its factors.
Depends on how many were possible. It is a B or B+. That is the grade and not the average. A average is reached by adding up all the grade and then dividing by the number possible, the number of 87 would be the number AFTER the number missed was subtracted from the total possible.
No. A complex number is a number that has both a real part and an imaginary part. Technically, a pure imaginary number ... which has no real part ... is not a complex number.
No. It is an imaginary (or complex) number.
No, it is an imaginary number which is a complex number.
