(-2i)(5i)(-1) how do you solve by simplifying showing the steps
1 answer:
This is the fundamental property of
i that you'll need to keep in mind when solving any problem with imaginary numbers (5i, 2i, 18i, etc.) or complex numbers (3+2i, 8-5i, etc). Squaring both sides of this definition, we also get that
Which we can use to solve this problem. We have:

Answer:
3 and 5
Step-by-step explanation:
factor tree is more appropriate.
Total marks in JEE = 400
Your marks = 70
Let your percent be x.
Then,
(x/100) × 400 = 70
=> x/100 = (70/400)
=> x/100 = 0.175
=> x = 0.175 × 100
=> x = 17.5
So, you got 17.5% marks.
is undefined when the denominator is 0. i.e. x - 3 = 0 or x + 2 = 0 or x - 5 = 0 i.e. x = 3 or x = -2 or x = 5.
Hence, Bobby is right.
