To find the value of the expression, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
First, simplify what's inside the parentheses:
(7 + 12) = 19
The expression becomes:
9[19 - 10]
Then, continue with the subtraction inside the brackets:
19 - 10 = 9
The expression becomes:
9[9]
Finally, multiply the numbers outside and inside the brackets:
9 * 9 = 81
Therefore, the value of the expression 9[(7+12)−10] is 81.
