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?
a little bit
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
Good we have \[14 \times 14 \times 14\] but your question asks for it in exponential form, so that will be?
Remember that exponents are this little number at the top |dw:1438983046511:dw|
can someone help me when youre done here?
Do you mean? \[14^3\]
ya i do
Yes, exactly :)
Simplify the expression 63 + 5(4 − 2). 28 36 226 234
Just follow the order of operations
But it seems you're missing information?
\[63 + 5(4 − 2) = 73\]
by the way 63 is 6 powerd by 3 and you have to simplify the answer
Ooh! Ok so use what I've told you already, what do you get
What does \[6^3 \] mean
Yes, 6 x 6 x 6
What is that?
Right, now we have 216+5(4-2) remember your order of operations? Do what's inside the bracket first
Good, keep going
i dont know what do do with the answers 221 and 2
Where did you get 221 from?
Not quite \[216+5(2)\] this is what we have, 5(2) just means multiply
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 :)
that my answer
That is the right answer!
5(4x + 2) ÷ 7y From the expression above, provide an example of each of the following: sum, term, product, factor, quotient, and coefficient. If any are not present, write "not present."
