OpenStudy (anonymous):

@narusasukid12

OpenStudy (anonymous):

@WWWHHHAAATTT?

OpenStudy (immanuelv):

when you have two equations with same base, can add or subtract the exponents

OpenStudy (wwwhhhaaattt?):

Is it negative or minus.

OpenStudy (immanuelv):

so for example x^5 x x^8 you can do 5+8

OpenStudy (anonymous):

negative

OpenStudy (anonymous):

ok so its 36*something @immanuelv would the -4 also make the 6 negative i cant remember i did this in like seventh grade soo yeah

OpenStudy (immanuelv):

no the base stays the same

OpenStudy (immanuelv):

lemme make sure

OpenStudy (wwwhhhaaattt?):

\[6^{2}x6-^{4}\]

OpenStudy (anonymous):

so it would be like 6 DIVIDED by6 divided by six and so on?

OpenStudy (immanuelv):

yeah the base stays the same so for 6^2 x 6^-4 you do the same its 6^(2-4)

OpenStudy (anonymous):

ok so the problem that patrick star has is 36*0.00077160493 right now. ill get the answer in just a bit

OpenStudy (wwwhhhaaattt?):

LLLLLLLLLLLLLLLEEEEEEEEDDDDDDDDDDDDDDDEEEEEEEEEEELLLLLLLLLLLLLLLLLL WWWWWWWWWWWWWEEEEEEEEEEEEEEEEEEEEWWWWWWWWWWWWWWWWWWWWWWOOOOOOOOOOOOOOOOOOO

OpenStudy (immanuelv):

you dont multiply the base so six doesnt change

OpenStudy (anonymous):

looks like its 0.02777777748 or 2.7^-10

OpenStudy (anonymous):

wait these r the answer choices

OpenStudy (anonymous):

1/36 1/6 1,296 36

OpenStudy (anonymous):

or just 36 because of the bases not changing sorry havent done this in two years so im a bit rusty on the topic

OpenStudy (anonymous):

uhhhh it was 1/36 ok more

OpenStudy (anonymous):

oh hmm wonder why

OpenStudy (anonymous):

1. Which of the following is an equivalent representation of 5-^4 ?

OpenStudy (anonymous):

thats -5^4 or 5^-4?

OpenStudy (immanuelv):

5^-4 is the same is 1/(5^4)

OpenStudy (wwwhhhaaattt?):

Patrick The glich is happening agian

OpenStudy (anonymous):

heres the answer choices 1/81 1/9 1/625 1/27

OpenStudy (anonymous):

i was jjust wondering which one it was _5^4 or 5^-4 because patrick put 5-^4.

OpenStudy (anonymous):

the last one

OpenStudy (anonymous):

so 5^-4?

OpenStudy (anonymous):

5-^4

OpenStudy (anonymous):

And @WWWHHHAAATTT? the @WWWHHHAAATTT? copyer wasnt me

OpenStudy (anonymous):

i dont get it where does the negative go in front of the 4?

OpenStudy (wwwhhhaaattt?):

Ok?

OpenStudy (anonymous):

heres an easier one

OpenStudy (anonymous):

Write the following expression using a single exponent. 5-6 × 57 5-13 50 5-42 51

OpenStudy (anonymous):

sry about that im in nith havent done eighth grade mathe my but just like shoved me into ninth grade with out making me do eight yet so its still hard a bit

OpenStudy (anonymous):

soooo..... whats the symbol that the question mark things are ommiting?

OpenStudy (anonymous):

8th is the hardest

OpenStudy (anonymous):

i had to take algebra 1 a THREE times because i didnt do eighth grade math

OpenStudy (anonymous):

simplify 3^4 × 3^2

OpenStudy (anonymous):

theres a x which is muliply between the??????????????>????????

OpenStudy (anonymous):

*,/,+, or -?

OpenStudy (anonymous):

x=multiply

OpenStudy (anonymous):

ok so (3*3*3*3) * (3*3) you could just say its like 3^6

OpenStudy (anonymous):

it=729

OpenStudy (anonymous):

729 or in exponential form 7.29*10^2

OpenStudy (anonymous):

729
