Answer: 5
Step-by-step explanation:
A exponent is the smaller number you will see sometimes on the top of a number or to the right of it but smaller than normal font
37/40 37 divide it by 25 and it comes out 37 and if you divide 25 into 1000 in comes out to be 40
In cases like these, you simply have to multiply the choices you have for each step.
In fact, you can choose between 4 different crusts. For each of these crusts you can choose 4 different sauces. This means that there are
choices at this point. In fact, if we call the crust options 1,2,3,4 and the sauce options A,B,C,D, the 16 possible combinations are

From here, you keep going multiplying the number of options for each step, for a total of

The second one is the only equivalent equation. Simply plug in each variable in each equation. And compare!
