how to enter log base in webwork

You need to enter something like: 2+3(sin(4x))^2 or 2+3sin(4x)^2. Cube roots and such x^(1/3) gives the cube root of x Other roots are also done with fractional exponents. Actually you could enter it as sin(t)^2 or even sint^2, but don't try such things unless you really understand the precedence of operations. 2x, 2 x or 2*x, also 2(3+4).

The best way to enter this in WeBWorK is by using interval notation: [0,infinity).
