<h2>The answer is 20² + 6(9 + 3) = 472</h2>
Use PEMDAS:
P) Parentheses first
E) Exponents (For example, Powers and Square Roots.)
MD) Multiplication and Division
AS) Addition and Subtraction

20² + 6 (9 + 3) = 400 + 6 (12) = 400 + 72 = 472
In the denominator as you can see that the bases are same, Therefore we're gonna add those powers.
something like this:
As we take the numerator to the denominator (when the base is same) then, the powers are turned to negative something like this:
So we'll do the same thing here,
Bases are same so once again add the powers,
and you'll get :
which is the same thing as
Answer: -5 • (r - 1)
Step-by-step explanation:
2x +6x = 8x
6-1 = 5
8x+5 is the answer
