Question

simplify the square root of 8n-27 devided by 4-n

Answer 1

kstatefan, do you know how to divide polynomials involving variables yet or no?

Answer 2

-8-27/(4-n)

Answer 3

I can show you if you need me to kstatefan. Just trying to assess how much I should go into detail

Answer 4

what is 8n/(-n) simplify to

Answer 5

-8 right?

Answer 6

yes

Answer 7

put that where the quotient goes and then multiply by the divisor to figure out what you need to subtract

Answer 8

k

Answer 9

oops i got the wrong remainder above

Answer 10

-8+5/(4-n)

Answer 11

so we have (8n-27)-(8n-32) which is ...

Answer 12

this is exponential and logarithmic functions we arent doing this right

Answer 13

oh thats the sqrt(8n-27)

Answer 14

i didnt see the sqrt sorry

Answer 15

so we aren't dividing. I would say it is already simplified

Answer 16

how do you use log or exponentiation here

Answer 17

exponential*

Answer 18

and i said it wrong the funtion is actually\[\sqrt{(8^{n}-27)\div (4^{-n})}\]

Answer 19

and i have no idea

Answer 20

=\[\sqrt{8^n*4^n-27(4^n)}=\sqrt{32^n-27(4^n)}\]

Answer 21

\[\sqrt{4^n}*\sqrt{(8^n-27})=2^n*\sqrt{(8^n-27)} \]
