Answer 1

^2 = SQUARED( to the second power)

Answer:

2. 2x times 2x equals 4x^2 since x times x equals x^2(and 2 times 2 equals 4. then positive i times negative i equals -i^2 which can transfer to be 1.

Step-by-step explanation:

2. 2x * 2x = 4x^2

   +i * -i = -i^2

   -i^2 can be transferred into positive 1.

   i is a variable. if you divide -i^2 by -i, then that equals i, which is 1.

3. The same thing as 2.^

   1 squared is 1. i squared is i^2. i^2 divided by i is i. i is 1. 1+1 is 2. Now put the 2 infront of the i to make 2i.
