The instrument used in this study is a non-test instrument, namely a validation questionnaire, and the data obtained from a validation questionnaire that has been filled out by the validator. The data will be analyzed descriptively quantitatively. Overall, the feasibility of the e-module assisted by algebrator software on the material of numbers and root forms obtained an average of 86.35%, so that the e-module assisted by algebrator software on the material of numbers and roots of class X SMK is interpreted as very valid to use. Kata Kunci: E-module, Algebrator Software, Exponents and Roots, Validity]]>
