When you multiply a same number but with different powers, you can simply add the powers together. So, in your question, add the powers -1 and -7 together.
7^(-1) x 7^(-7) = 7^(-8)
When you divide a same number but with different powers, you subtract the power at the top with the power from the denominator. So, -8 - (-7) = -1.
7^(-8) / 7^(-7) = 7^(-1)
So your answer would be 7^(-1).
Hopefully my explanation was clear?
20 x 1/2 = 10
There are 10 rows that are planted with corn.
It means the same used in a question like this, is 25 as much as 25.
Answer: 79%
That’s because it’s the middle probability it can’t be others because they are too high it too low
P = The kitchen is clean → TRUE
Q = The bedroom is clean → FALSE
1) If P is true, then Q is true. → False statement
2) Statement Q is true if and only if P is true. → False statement
3) Both p and q are true. → False statement
4) Statement P or Q is true. → True statement ⇒ Statement P is true.
The answer is: The statement "Statement P or Q is true" is true.
There you go! I really hope this helped, if there's anything just let me know! :)
