Answer 4

what do you not understand about it

Answer 5

Can you check if it is right?

Answer 6

The ones I circled is what I picked, the green question mark is what I think can be possible. red X is not the answer I ruled out.

Answer 7

i see, there are just a couple properties you shold remember...

Answer 8

for fractions like that, if you move from top to bottom or bottom to top, the exponent sign will change(+/-)

so for question 3...

Answer 9

Ok, I am writing this down, I have to go brb real quick, I will come back

Answer 10

ok, here look at the second section, exponent properties in this thing

Answer 11

The first question you have wants to know which ones multiply the exponents, like in property
\[(a^n)^m\]

Answer 12

an exponent raised to another exponent like that, you multiply them
\[\large (a^m)^n=a^{m*n}\]

Answer 13

you add the exponents when you are multiplying together the same bases like this property

\[\large a^m * a^n = a^{m+n}\]

and recall if you change side of fraction, the sign changes

\[\large \frac{ 1 }{ a^m } = \frac{ a^{-m} }{ 1 }\]

Answer 14

those 3 things are all ya have to remember here...

so for the first question first answer,, you have 2^9/2^7 ,

apply the fraction rule furst to move the 2^7 up top... then you have

\[\large \frac{ 2^9 }{ 2^7 } = 2^9 * 2^{-7}\]

Answer 15

then the second rule shows that for those multiplied bases, you have to add the exponents, so in this one you do not multiply the exponents... no
