-125 is NOT an imaginary number.
57!
It is 8 and 125/1000. You can simplify the fractional part if you so wish.
25 over 16.
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
57!
Already is. You can not simplify it anymore.
1.25 IS a rational number. The fact that it is expressed as a terminating decimal does not mean it is not rational. As a ratio, it can be written as 125/100. You may simplify that ratio if you so wish.
The complex conjugate pair, -125 - 233.1845*i and -125 + 233.1845*i where i is the imaginary square root of -1.
It is 8 and 125/1000. You can simplify the fractional part if you so wish.
-12 = 4 x 3 x -1 so sqrt = 2i root 3
Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.
125/1000 or 1/8
25 over 16.
no - it is not divisible, but is can be expressed as 0.416
yes you can the answer is 25/32
Yes I can. I would divide the numerator and the denominator of that fraction each by 125 .
