The values are 5i, -4, 2√2i, -16, -50i and i.
<h3>What is an imaginary number?</h3>
An imaginary number is a number that, when squared, has a negative result, and is defined by its property i² = −1 or i = √-1.
Given are numbers,
1) √-25 = √25*√-1 = 5i
2) √-2√-2 = 2i*2i = 4i² = -4
3) √-8 = √8*√-1 = 2√2i
4) (4i)² = 16*i² = -16
5) (2i)(5i)² = 2i*25i² = 50i³ = -50i
6) i²*i³* = -1*(-i)*1 = i
Hence, The values are 5i, -4, 2√2i, -16, -50i and i.

Answer:
2
Step-by-step explanation:
1+1=2
X = 5 - y...so sub 5 - y in for x in the other equation
5(5 - y) - 4y = 7...distribute thru the parenthesis
25 - 5y - 4y = 7...simplify
25 - 9y = 7....subtract 25 from both sides
-9y = 7 - 25
-9y = - 18...divide both sides by -9
y = -18/-9
y = 2
x = 5 - y
x = 5 - 2
x = 3
solution is (3,2)
