Help. I don't know how to- ;c
Which part do you have to simpilfy?
@snowflake0531 - @supie - ?
Well, I am not sure which part I am supposed to simplify.
You see, I was never taught how to simplify these and I have already contacted my teacher and she says I should know. So I'm left dumbfounded.
Simplify all this? Is this one equation, or no?
I mean expression, not equation. ._.
These are multiple expressions. I believe each and everyone is supposed to be simplified.

let supie do it, he knows his stuff xd
Is 3 x 10^3 times 4 x 10^5 simplified supposed to be.. \[12~ times ~10^8\]
Do you want me to walk you through each one?
Have you learned the properties of exponents yet?
I- Idr or idk. I might've. IDKK lc

The exponent rules \( (a^b)^c = a^{bc}\) \( \dfrac{x^y}{x^z} = x^{y-z}\) \( a^b \times a^c = a^{b+c}\)
Oh yah, I remember those.
There one or two more exponent properties but these are the only ones you need to solve the remaining questions on your worksheet
\[3*10^{3}*4*10^{5}\] \[\frac{ 3^{4} }{ 3}\] \[(4^{2})^{3}\] \[\frac{ 7^{10} }{ 7^{6} }\] \[\frac{ 8*10^{6} }{ 2*10^{3} }\] \[5^{3}*5\] That was a lot to right. ._. So, those are the expressions.
Let's take a look at your second expression that you have to simplify. \(\dfrac{7^{10}}{7^6} =\) You need to apply this rule: \(\Large \dfrac{a^b}{a^c} = a^{(b-c)}\)
Do I divide/ or multiply or add both a's together?
The 'a' just stays the same You only subtract the exponents
So it's \[7^4\]
Yes
For your third expression, keep in mind that \( 3 = 3^1\) How would you simplify \(\dfrac{3^4}{3^1} = ?\)
3^3?
Yes. Next one now \( \dfrac{8 \times 10^6}{2 \times 10^3} = ?\)
I know it would be to the power of 3, but I am stuck because of the 8 and 2.
Just divide those numbers like normal
\[4^3?\]
It won't have an exponent. You can think of it like this \( \dfrac{8 \times 10^6}{2 \times 10^3} = ?\) \( \dfrac{8 \times 10^6}{2 \times 10^3} = \dfrac{8}{2} \times \dfrac{10^6}{10^3} = ?\)
I- Idk.
What is \(\dfrac{8}{2} = ?\)
4.
We have now: \( \dfrac{8 \times 10^6}{2 \times 10^3} = 4 \times \dfrac{10^6}{10^3}\) What is \( \dfrac{10^6}{10^3} = ?\)
10^3?
Yes. Now put it all together. \( \dfrac{8 \times 10^6}{2 \times 10^3} = 4 \times \dfrac{10^6}{10^3} = \boxed{4\times 10^3}\)
Oh~~~ That makes some sense now.
Good. Next expression now. \( (4^2)^3\) Use the following property: \(\Large (a^b)^c = a^{bc}\) You just have to multiply the exponents
So it is \[4^6?\]
Yes. Now your last expression. \( 5^3 \times 5^5\) Use the following property: \(\Large a^b \times a^c = a^{b+c}\) Just add the exponents
\[5^8?\]
That is correct!
Yay, Thanks so much Tranq.
You're welcome, Astrid!
