Final answer:
The verbal expression is 'three multiplied by m raised to the fifth power, plus nine,' and involves understanding integer powers and working with exponential expressions.
Step-by-step explanation:
The verbal expression of the sum of three times m to the fifth power and 9 can be written as "three multiplied by m raised to the fifth power, plus nine". To further clarify, when dealing with the cubing of exponentials, such as m5, you would cube the digit term in the usual way and multiply the exponent by 3. However, in this case, we are not cubing but simply multiplying m5 by three and adding nine to it. This exercise helps in understanding how to work with integer powers and perform operations on exponential expressions.
