8.28 / 0.18 = 46
So, Tammy's call lasted 46 minutes
Hope this helps :)
So, the questions is 6^(-6) * 6^(-1).
Remember, whenever we are multiplying two numbers with the same base and with different exponents, we should always add the exponents and keeps the same base.
In this ,case it is, -6 and -1.
-6 + (-1) = -7
So the answer would be 6^(-7).
