Label each of the following statement as true or false. if false, replace the underlined word or expression to produce a true statement

7.) False, you would have to expand the exponents with the variable too.  So you would end up getting a whole different equation. And you use the reciprocal and switch them around. You would end up getting:
-25+5x+2/ -1x and switch them around and you get 1x/25+5x+2.

8.) True.

9.) True

10.) True.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
