How do I use the calculator to do these formula's
Can someone tell me what is the process on how to calculate the following examples on the calculator. In other words I don't know how to do these on the calculator. I hope these examples make sense. Thanks

Example 1.
17,500 × (1 + x/100)5 = 26,000 // 5 is the power of
(1 + x/100)1/5 = 26,000/17,500 = 1.4857 // 1/5 is the power of

Example 2.
Area in 2000 × (0.99)20= 1,545 × (0.99)20= 1,264 // 20 is the power of

You should have a button with $x^y$ or $^$ on. These indicate powers (the latter is also used to denote powers in plain text)

(1+x/100)^(1/5) is probably input as
Code:

`( 1 + x / 1 0 0 ) ^ ( 1 / 5 )`
