Answer:

Step-by-step explanation:
We want to simplify:

We rewrite as positive index to get:

This simplifies to

This will finally give us:

We cannot simplify further.
Hence the simplest form is 
To add, subtract, multiply or divide the number given to get a whole number or an integer
If it’s a triangle then it has to equal 180
so 48+54+x=180
48+54=102
180-102=x
x=78
Answer:
7.25
Step-by-step explanation:
200m/s^6 = m/3^6
s^6 = 200*3^6
s = 3*200^(1/6) = 7.25 mi/hr
