Given:
Standard form and expanded notation
Find-:
The number shown in standard form and expanded notation
Explanation-:
The standard form is
Standard form = The standard form is

For example, is

The expanded form is
The expanded = Expanded form is a way to write a number by adding the value of its digits. We can use a place value chart to determine the value of a number's digits.
For example
Answer:
the total of angle's in traingle is 180
so 85+53+c=180
c=180-138
c=42

Answers: Choice B, Choice C</h3>
The rule we use here is 
If the font size is too small, then it says (a^b)/(a^c) = a^(b-c)
We subtract the exponents when dividing exponentials like this. The bases must be the same.
So this means the exponents 13 and 3 subtract to get 13-3 = 10
We either have an exponent of "13-3" or an exponent of "10" as an equivalent expression. The base stays at 2 the entire time.
Answer:
I think it's C but I'm not too sure
