What value divided by 81 equals 8?

In other words, what would the dividend be if the divisor were 81 and the quotient 8?

To find the answer, just multiply the divisor with the quotient: 81 × 8 = 648

To prove this, let's compute 648 divided by 81: 648 81 = 8

How does it work?

Asking which value divided by 81 gives a result of 8 is equivalent to solving the following equation:

x 81 = 8

  1. We need to isolate x, so multiply both sides by 81: 81 x 81 = 81 × 8
  2. 81 x 81 is equivalent to 81 81 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 81 × 8 = 648

So, if the divisor is 81 and the quotient is 8, the dividend is 648.
