For this case we must find an expression equivalent to:

By definition of power properties we have to meet:

Then, we can rewrite the expression as:

Answer:

The answer would be 
In 1.23, we know that 1 is a whole number and .23 is part of a whole, so it is a fraction.
.23 can be written as
because the decimal is till the hundredths place.
We cannot simplify
any further so we leave it as is.
The answer would then be
.
If you use the midpoint formula which is [(X1+X2)/2,(Y1+Y2)/2], you will get your midpoint is [(a+b)/2,(b+c)/2]
