862.5
[tex] \\ [/tex]
SOLUTION:
First we need to multiply the power of 10 (²³) to be a real number.
So we need 10 × 23 = N
[tex] \\ [/tex]
Multiply 23 to 1
23 × 1 = 23
then add the 0 on the 10 which we remove amd set aside the number 0
So the answer is 230.
10 × 23 = 230

Then we will multiply 3.75 to 230
3.75 × 230 = 862.5
So the final Answer is 862.5
