What value divided by 81 equals 10?
In other words, what would the dividend be if the divisor were 81 and the quotient 10?
To find the answer, just multiply the divisor with the quotient: 81 × 10 = 810
To prove this, let's compute 810 divided by 81:
How does it work?
Asking which value divided by 81 gives a result of 10 is equivalent to solving the following equation:
- We need to isolate x, so multiply both sides by 81:
- is equivalent to , which simplifies to (or just ).
- Thus:
So, if the divisor is 81 and the quotient is 10, the dividend is 810.
