Jimmy went to the toy store. he saw 23 wooden trains and 41 plastic trains. how many more plastic trains than wooden trains did he see?

This is a simple subtraction problem.  To find out how many more plastic trains there were than wooden trains, subtract the number of wooden trains from the number of plastic trains. 

41 (plastic) - 23 (wooden) = 18 more plastic than wooden

a. is correct

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
