Answer: a = 17/6
Step-by-step explanation:
I will use two laws of indices to solve this question
1. x^a / x^b = x^(a-b)
2. x^a = x^b, => a = b
Using both laws
x³/x^1/6 = x^a
x^(3-1/6) = x^a
3 - 1/6 = a
a = 3 - 1/6
a = (18 - 1)/6 using LCM
a = 17/6

Answer:
94
Step-by-step explanation:
the sum of the angles in a triangle add up to equal 180
180-73-13=94
Answer:
240
Step-by-step explanation:
2 is 1 + 1 so 120 + 120 must be the equivalent of 2.
Answer:
D) 1
Step-by-step explanation:
When you start raising i to certain powers, you begin to notice a pattern.

This cycle repeats forever. Since 84 is a multiple of 4, i^84 must be 1. Hope this helps!
