help will give medal and fan !!!

Answer 1

@mathstudent55 @zepdrix help!!

Answer 2

Answer 3

\(\Large\rm V=\ell\cdot\mathcal w\cdot\mathcal h\)
But since it's a cube, all the dimensions are the same,\[\Large\rm V=\ell^3\]And they told us the side length is, \(\Large\rm \ell=2n^6\)

Answer 4

\[\Large\rm V=(2n^6)^3=2^3(n^6)^3\]

Answer 5

Remember your exponent rule?
Exponent and another exponent, what do we do? :U

Answer 6

multiply ?

Answer 7

Good good good, multiply :)
\[\Large\rm (x^a)^b=x^{ab}\]

Answer 8

umm

Answer 9

this is confusing omg

Answer 10

So we multiply the 6 and 3, yes?

Answer 11

yeah 18

Answer 12

Understand why I put a 3 on the 2?
With exponents we have to apply the exponent to EVERYTHING in the brackets.\[\Large\rm (ax)^b=a^bx^b\]

Answer 13

\[\Large\rm V=(2n^6)^3=2^3n^{18}\]

Answer 14

ohh sorta starting to understand

Answer 15

what do you think the answer is? i'm taking a timed test so kind of in a hurry

Answer 16

Do you understand how to calculate 2^3? :o

Answer 17

yeah !

Answer 18

This is the point we got up to:\[\Large\rm V=2^3n^{18}\]

Answer 19

the volume of a cube is v=a^3 so the edge(a in the formula) is 2n^6 right? ok so once you have that you just plug it in to the formula...... so, V=(2n^6)^3 then solve from there which should give you the answer, which is 8n^18 cubic unit, and that is the first answer choice @karendiaz123

Answer 20

thanks !

Answer 21

did you understand? @karendiaz123

Answer 22

yeah took me a while but i got it

Answer 23
