Question

Which expressions are listed in the simplest form? Check all that apply.

Answer 1

I don't see the expressions to check — could you paste or type the answer choices here (or upload a screenshot)?

While you do that, here are the rules I’ll use to decide whether an expression is in simplest form:
- For rational expressions: numerator and denominator have no common factors (fully reduced). No removable factors remain.
- For numerical fractions: reduced to lowest terms.
- For polynomials: like terms combined, no parentheses left to expand unless factored form is required.
- No negative exponents (rewrite as positive exponents in numerator/denominator).
- Radicals: no perfect powers inside the radical; no radicals in the denominator (rationalized) unless the problem allows them.
- No unnecessary complex factors or terms (e.g., write 2x instead of x + x).
- Trig/absolute/special forms: simplified according to standard identities if appropriate.

Examples:
- (6x)/(3) is not simplest — simplify to 2x.
- (x^2 − 1)/(x − 1) is not simplest — simplifies to x + 1 (for x ≠ 1).
- x/(√2) is not simplest — rationalize to (x√2)/2.
- x + x is not simplest — combine to 2x.
- (3x)/(6) is not simplest — simplify to x/2.

Send the choices and I’ll mark which are in simplest form and show any needed simplifications.
