Step-by-step explanation:

To solve this problem we must solve all 4 operations.

For the first one we have:

When we have multiplication of powers of equal base (10) the same base is placed and the exponents are added

So:

Therefore the answer to this question is correct.

For the second question we have:

Then following the same procedure as in the previous question we have:

Then the answer shown in the statement is not correct, because 10 must be squared, product of the sum of its exponents (1 + 1)

For the third question we have:

Then it is verified that the answer for this operation is no correct

Finally, for the fourth question we have:

This we can write it as:

In division of powers of equal base (10 in this case) the same base is placed and the exponents are subtracted:

Finally, the problems that show correct answers are:
