Solution: The numerical expression is
8* (9+11.3)
and the value of this expression is 162.4.

Step-by-step explanation:

The sum of 9 and 11.3 is written as
(9+11.3).

The product of 8 means the expression should multiply by 8.

According to the given information the the product of 8 and the sum of 9 and 11.3 is written as
8* (9+11.3).

To evaluate the value of the expression first we have to add 9 and 11.3 after that multiply the result by 8.


8* (9+11.3)=8* (20.3)\\8* (9+11.3)=162.4

Therefore, the numerical expression is
8* (9+11.3)
and the value of this expression is 162.4.

Answer:

162.4

Step-by-step explanation:

To write the numerical expression for the product of 8 and the sum of 9 and 11.3 we need to follow these steps:

Sum of 9 and 11.3 is given as follows:


(9+11.3)

Now the product of 8 and the sum of 9 and 11.3 is:


8(9+11.3)

So the required expression is:


8(9+11.3)

Solving the above expression we get:


8(9+11.3)=8(20.3)=8 * 20.3=162.4
