### Where can I get instructions for using an unidentified calculator?

If it has no name , it is probably a cheap one without many features. Most basic calculators have digit keys to enter numbers, and some operation keys to specify operations to be performed on the numbers entered.
Operation keys are +(add), -(subtract), X (multiply) , and / (divide). You may have an equal sign to display the result.
You may also have a square root key.
For an operation +,-,x, or / you enter the first number, then the operation key, then the second number and the = key. The result will be displayed.
For a square root , enter a positive number then press the square root key.

Good luck.

### 4 squre root 81

Take the fourth root. The square root, denoted by a 2 on top of the "root thing" or more commonly without a number at all, is the second root.

Usually the easiest way to calculate the fourth root is to calculate the square root of the square root. So in this case the fourth root of 81 is the square root of the square root of 81. The square root of 81 is 9, the square root of 9 is 3.

### Solve x^2-22x=10

Just complete the square
x^2-22x-10=x^2-2(x)*11+11^2-11^2-10=(x-11)^2-121-10=(x-11)^2- 131.
Use the identity a^2-b^2=(a-b)(a+b) with a=(x-11) and b= square root (131)
Solutions are x1= 11 + square root (131) and x2=11-square root (131).
By the way, the calculator you are refer to cannot perform symbolic algebra calculations.
