Can Someone Explain How In The World Is The Answer To Question 11 Is 15 class=

Sagot :

Step-by-step explanation:

Hey there!

When you move a number from the denominator that has a negative exponent to the numerator, that exponent becomes positve.

In this case, the 5 to the power of -1 will turn to 5 to the power of 1 when moved to the numerator (5 to the power of 1 is 5)

Now when we multiply 5 by -3, we get the answer -15!
