# Math Help - How to read basic formula

1. ## How to read basic formula

Hello everyone.

I'm not a big mathematician, which gives me some troubles in reading formula notations. I hope that someone in here can help me translate the notation below into a non-math language, like: multiple X by Y and then subtract Z

I have all the varaibles W and S, and eulers constant. I just can't figure out how to calculate X.

Dear McGyver,

$X=(1-e)\frac{8}{5}\left(\frac{S}{W}\right)^{\frac{7}{5} }=\frac{8\times(1-e)}{5}\times\left(\sqrt[5]{\frac{S}{W}}\right)^7$

Therefore you substract e (eulars constant) by 1, multiply the answer by eight, divide it by 5. Take this result as A.

Now you can divide S by W then multiply the answer by itself seven times (take the seventh power), and take the fifth root of the answer. Take this result as B.

Multiply A and B.
