To input powers use the ^ symbol.

For example to input $x^3$ type x^3.

To input $2^{x+1}$ type 2^(x+1). Note you need to use brackets here.

Input $x^{\\var{a}}$=[[0]]

Input $3^{2x+5}$=[[1]]

To input $3x^2+5x-2$ type 3x^2+5x-2

Input this polynomial: $\\simplify[all]{{a}*x^{b}+{c}*x+{d}}=\\;$[[0]]

To input two variables multiplied together you need to use * for multiplied.

For example to input $ab$ you need to type a*b.

Input the following:

$xy$=[[0]]

$xyz$=:[[1]]

If you want to input such an expression into the system you HAVE TO BE CAREFUL AND USE BRACKETS or mistakes will occur.

To input $\\displaystyle \\frac{2-3x}{5+4x}$ type (2-3x)/(5+4x)

Input the expression: $\\displaystyle \\frac{\\var{b}+\\var{a}y}{\\var{d}+\\var{c}z}$= [[0]]

To input square roots you need to write \"sqrt(..)\"

For example to input $\\sqrt{x}$, type sqrt(x)

Input the following

$\\sqrt{y}=$[[0]]

$\\sqrt{2x+3}=$[[1]]

$\\sqrt{\\frac{L}{g}}=$[[2]]

$\\sqrt{\\frac{2x+7}{x^2+1}}=$[[3]]

This first question just goes through how to input different algebraic equations into the computer.

You can refer back to this question when doing the other questions if needed.

Note that what the computer understands by what you have inputed appears to the right of the box you are typing in.
