Answer:
Any radical in the form can be written using a fractional exponent in the form . The relationship between and works for rational exponents that have a numerator of 1 as well. For example, the radical can also be written as , since any number remains the same value if it is raised to the first power.
Step-by-step explanation:
Answer:
f(x) and its inverse are the same
Step-by-step explanation:
<u>The inverse function
</u>
If y=f(x), the inverse function 
is defined such as
To find the inverse function, there is a practical method:
a) Change letters x for y and vice-versa
b) Isolate y in terms of x only
c) 
In our case, 
a) Interchanging letters
b) Isolate 
c) 
As we can easily see, f and its inverse are exactly the same
triangle B. because congruent is supposed to be the same shape same size but triangle b is same shape but a different size
True
<span>There is some disagreement whether parallelograms, which have two pairs of parallel sides, should be regarded as trapezoids. Some define a trapezoid as a quadrilateral having only one pair of parallel sides (the exclusive definition), thereby excluding parallelograms.</span>
