If you wanted to calculate it, there it is: ( 9 8 โ€‹ ) 2 ( โˆ’ 81 ) + 10 โˆ’ 9 โ€‹ 5 3 โ€‹ โ€‹ = 81 64 โ€‹ โˆ— ( โˆ’ 81 ) + 5 3 โ€‹ โˆ— โˆ’ 9 10 โ€‹ = โˆ’ 64 + 3 โˆ’ 2 โ€‹ = = โˆ’ 64 โˆ’ 3 2 โ€‹ = 3 โˆ’ 192 โˆ’ 2 โ€‹ = 3 โˆ’ 194 โ€‹

To evaluate the expression, we calculate ( 9 8 โ€‹ ) 2 โ‹… ( โˆ’ 81 ) to get โˆ’ 64 and then calculate 5 3 โ€‹ รท 10 โˆ’ 9 โ€‹ to get 3 โˆ’ 2 โ€‹ . Finally, combining these results gives us 3 โˆ’ 194 โ€‹ .
