Answer:
Step-by-step explanation: To express the given operations in a mathematical expression, you would multiply 9 by b and then multiply c by the result. Mathematically, this can be represented as: (9·b)·c
This expression first multiplies 9 by b, and then the result is multiplied by c. The parentheses are used to indicate the order of operations, ensuring that the multiplication involving b is performed first before the final multiplication with c
