Set the denominator equal to zero and exclude those values
For even roots, require the radicand to be greater than or equal to zero
For odd roots, no restriction from the root itself
For logarithms, require the argument to be greater than zero
For fractions inside fractions, exclude any values that make an inner denominator zero
For rational exponents, apply root restrictions based on the denominator of the exponent in lowest terms
For expressions with multiple parts, combine all restrictions using intersection
Solve each restriction algebraically
Write the domain as all real numbers except the excluded values, or in interval notation
