Remember
i²=-1 so
i³=-i
i⁴=1
so
5i⁴+2i³+8i²-4
5(1)+2(-i)+8(-1)-4
5-2i-8-4
-7-2i is the form
Answer:
a=2/3
Step-by-step explanation:
3(4a+1)+3a=13
12a+3+3a=13
15a+3=13
15a=10
a=2/3
4³ ⋅ (100 ÷25) − 5^0
[parenthesis goes first, then exponents]
[any coefficient with zero exponent is equal to 1]
64 · 4 - 1
[multiplication, then subtraction]
256 - 1

There are 5 points in the figure (<em>V</em>, <em>W</em>, <em>X</em>, <em>Y</em>, and <em>Z</em>)
<em>a</em> refers to the line through <em>V</em>, <em>W</em>, and <em>X</em>.
<em>b</em> refers to the line through points <em>Y</em>, <em>W</em>, and <em>Z</em>.
<em>D</em> refers to the plane that contains all 5 points as well as the 2 lines.
