Please thoroughly explain how this is the correct answer. Thank you!

see below

Step-by-step explanation:

that is what you called nth Root

Just like the square root () is used two times in a multiplication to get the original value.

And the cube root () is used three times in a multiplication to get the original value.

The nth root is used n times in a multiplication to get the original value.

ex:

x⁵ = 13  >>>>    x = ⁵√13

x²⁰ = 13 >>>>    x = ²⁰√13

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is

happy to

pls mark as brainliest.
