<span>Units are used as a standard for measurement of the same quantity. It is a definite magnitude of the quantity that is defined by a convection.
Without them we could not be able to measure things.
All physical quantities have their units, For example: length is measured in meters, weight is measured in kilograms, power is measured in watts,...
With units we can understand "physical" problems and have an exact answer of the problem.</span>
Answer: 1
Step-by-step explanation:
To Evaluate the expression -(1/3)^0 and (-9)^0
It is important to note that any number raised to the power of 0 is 1, therefore,
-(1/3)^0 = -1
(-9)^0 = -1
(-1) x (-1) = +1
I hope this helps
The answer is d. They are similar by angle angle
This is the fundamental zero additive rule
x - 0 = x
which means that for the set of real numbers, there exist a number such that if added (or subtracted) from any other will not affect such number.
