Answer: 
Step-by-step explanation:
1. To simplify the expression given in the problem, you must apply a property of exponents called Quotient of powers, which states that when you divide two powers that have the same base, you must subtract the exponents.
2. Keeping this property on mind you have, you can rewrite the expression as following and simplify:

Answer:
11.2 mm
Explanation:
Given a right angle triangle, In order to find the third side: Use Pythagoras Theorem: a² + b² = c²
Insert Values:
x² + 3.8² = 11.8²
x² + 14.44 = 139.24
x² = 139.24 - 14.44 (subtract)
x² = 124.8
x = √124.8 (square root)
x = 11.1714 ≈ 11.2 (rounded to 3 significant figures)
I think the mean with outliers excluded are called trimmean.
1/2+3/x = 3/4
3/x = 3/4 - 1/2
3/x = 3/4 - 2/4
3/x = 1/4
12 = x
the denominator are not 0 and still can solve it with a value of 12
