Let's rearrange the following equation so that we can reveal a secret message!
We are going to apply various properties of equality. Let's start by mutiplying both sides of the equation by r squared.
Next we are going to exponentiate both sides of the equation by the natural number e. Remember that the number e and the natural logarithm (log base e) are inverse operations so they cancel out.
Then we will add the expression sa to both sides of the equation.
From here we will multiply both sides of the equation by m.
Having multiplied by m let's go ahead and apply the distributed property on the left side of the equation and distribute the variable m to both terms.
Now let's subtract the term msa from both sides.
Finally we apply the commutative property of multiplication to y times r squarred term and rewrite it as r times r times y. We also apply the commutative property of multiplication to the m times s times a term and rewrite it as m times a times s. We also color the left side of the equation green and the right side of the equation red given us our secret message!
