picture of question below.

Nnesha (nnesha):

\[\huge\rm \frac{ x^m }{ x^n } =x^{m-n}\] exponent rule!

OpenStudy (lisa2345):

so its B?

Nnesha (nnesha):

how did you get B ? r^2 can be written as r times r \[\huge\rm \frac{ r \times r }{ r \times r }\] simplify

OpenStudy (lisa2345):

so its A?

Nnesha (nnesha):

how ?? :-)

OpenStudy (lisa2345):

because the R cancels out?

Nnesha (nnesha):

great!

OpenStudy (lisa2345):

I need quicl help on like 4 more

Nnesha (nnesha):

okay i have 2 minutes :-)

OpenStudy (lisa2345):

Nnesha (nnesha):

show your work and let me know what did you get ? ;-)

OpenStudy (lisa2345):

2x^6 ?

Nnesha (nnesha):

12/24 = ?

OpenStudy (lisa2345):

0.5

Nnesha (nnesha):

yep but u need it infraction form

OpenStudy (lisa2345):

x ?

Nnesha (nnesha):

what ?

OpenStudy (lisa2345):

C?

OpenStudy (lisa2345):

is the answer C ?

Nnesha (nnesha):

yep right

OpenStudy (lisa2345):

Nnesha (nnesha):

anything to the 0 power is equal to what ?? do you know ?

OpenStudy (lisa2345):

nothing?

Nnesha (nnesha):

equal to 1

OpenStudy (lisa2345):

so 0 is one?

Nnesha (nnesha):

\[\huge\rm (2)^0 = 1 ~~~(Nnesha)^0 = 1\]

Nnesha (nnesha):

^

OpenStudy (lisa2345):

so the answer is A

OpenStudy (lisa2345):

??

Nnesha (nnesha):

x^0 = ?

OpenStudy (lisa2345):

1

Nnesha (nnesha):

yes right so what you should hve left ?

OpenStudy (lisa2345):

the answer is C?

Nnesha (nnesha):

you just said x^0 =1 so C is not right \[\huge\rm 6\color{red}{x^0}y^5\] x^0 =1 so replace that by one that's it

OpenStudy (lisa2345):

its B?

Nnesha (nnesha):

\(\color{blue}{\text{Originally Posted by}}\) @Nnesha you just said x^0 =1 so C is not right \[\huge\rm 6\color{red}{x^0}y^5\] x^0 =1 so replace that by one that's it \(\color{blue}{\text{End of Quote}}\) ^^^^^

OpenStudy (lisa2345):

I don't understand is it D?

Nnesha (nnesha):

there are not same bases all u need to do is apply 0 exponent property x^0 = 1 so just replace x^0 by 1 and 6 y^5 stay same :-)
