To verify the equation 54 ÷ 9 = 6, we need to use the inverse operation of division, which is multiplication.
To check if the division is correct, we can multiply the result (6) by the divisor (9) and see if we get back to the original number (54). So we perform the following calculation:
6 × 9 = 54
Since this gives us the original number 54, we confirm that the original equation is correct. Therefore, the inverse operation used to verify this equation is multiplication.
