It's p = 6/(x+a).
Multiply both sides by p to get 6 = p(x+a), then divide both sides by (x+a) to get 6/(x+a) = p.
6.37² x 3.1
First is Exponents (6.37²):
40.6 x 3.1
Then, Multiplication:
40.6 x 3.1 = 125.9.
To remember the order of operations, the term PEMDAS can be used. (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.)
You do the equation in the order of the letters.
Example:
(5-2)5 + 2² / 6 -1 = ?
First, Parentheses:
(3)5 + 2² / 6 - 1
Then, Exponents:
(3)5 + 4 / 6 - 1
Then, Multiplication:
15 + 4 / 6 - 1
Then, Division:
15 + 0.7 - 1
Then, Addition:
15.7 - 1
Then, Subtraction:
14.7
So that means, (5-2)5 + 2² / 6 -1 = 14.7
