Webb2 · ___ = 1. Notice that in each case, the missing number was the reciprocal of the number. We call 1 a the multiplicative inverse of a ( a ≠ 0). The reciprocal of a number is its multiplicative inverse. A number and its reciprocal multiply to 1, which is the multiplicative identity. We’ll formally state the Inverse Properties here: WebbSimplify by Using Formula : (2x + 3y) (2x - 3y) CISCE ICSE Class 9. Question Papers 10. Textbook Solutions 19278. Important Solutions 16.
