For the entire radical √125x^3, state the restrictions on the variable. Then express as a mixed radical my work: =√5x * 5x * 5x =5√5x Restriction x ≥ 0, x ∈ R What did I do wrong? Dec 15 | Maralyn from Alexandria, VA | 1 Answer | 0 Votes Mark favorite Subscribe Comment
f(x) =√(125 X^3) √( 125X^3 )≥ 0. 5 X √(5 X ) , 5X≥0. , X ≥0 / square roots are denied only for positive numbers. Dec 15 | Parviz F. Comment
