This seems fun, ok so you know that \[y^2 = y \times y\] \[y^5 = y \times y \times y \times y \times y\] right? The exponent just means you multiply it by itself that many times, does that make sense so far?

Ok, so when we talk about areas we have 2 dimensions that would mean we have something squared, when we talk about volume we have 3 dimensions so we cube it, let me draw what I mean. |dw:1438982740847:dw| so A here represents area and we know to get area of a square we write it as \[a^2 = a \times a~~~~14^2 = 14 \times 14\] now we have a cube and to find it's volume, we deal with 3 dimensions so it looks as such |dw:1438982814212:dw| notice all the dimensions in a cube are the same so we have volume as \[V =a^3\] so what can we conclude our answer to be? (I know this might be a lot at once, but I hope it helps you understand)

14.14.14 i guess
Astrophysics
  • Astrophysics
Good we have \[14 \times 14 \times 14\] but your question asks for it in exponential form, so that will be?
anonymous
  • anonymous
14*3

Simplify the expression 63 + 5(4 − 2). 28 36 226 234
Astrophysics

Just follow the order of operations
Astrophysics

But it seems you're missing information?
Astrophysics

\[63 + 5(4 − 2) = 73\]
anonymous
  • anonymous
by the way 63 is 6 powerd by 3 and you have to simplify the answer
Astrophysics
  • Astrophysics
Ooh! Ok so use what I've told you already, what do you get
Astrophysics
  • Astrophysics
What does \[6^3 \] mean
anonymous
  • anonymous
6.6.6
Astrophysics
  • Astrophysics
Yes, 6 x 6 x 6
Astrophysics
  • Astrophysics
What is that?

216

Right, now we have 216+5(4-2) remember your order of operations? Do what's inside the bracket first
anonymous
  • anonymous
4-2=2
Astrophysics
  • Astrophysics
Good, keep going

216+5+221

i dont know what do do with the answers 221 and 2
Astrophysics

Where did you get 221 from?
anonymous
  • anonymous
216+5
Astrophysics
  • Astrophysics
Not quite \[216+5(2)\] this is what we have, 5(2) just means multiply
Astrophysics

5 x 2 = ?

When you get into higher math, we don't always put the multiplication sign, we just put brackets or a dot

Yes 226 :)
