Answer 1

Please use the ^ symbol to indicate exponents... Please...

Answer 2

This?

Answer 3

i forgot i remember u i was about to fix it sry

Answer 4

\[x^{8-5} + 3x^{5-5} = x^3 + 3x^0 = x^3+3\]
See how this works now? :-)

Answer 5

You are factoring out a x^5

Answer 6

dividing exponents, you subtract the power #'s

Answer 7

and anything to the 0 power is ALWAYS 1 (because mathematicians said so), even \( 0^0 \)

Answer 8

x^3+3x=x^5???

Answer 9

no...
\[x^8 + 3x^5=x^5(x^3+3) \]

Answer 10

look at the numbers on the exponents ;-)

Answer 11

And re-read what I wrote above, it should click. If you're factoring stuff up...

\[ax+bx \rightarrow \frac{ax+bx}{x}=x(a+b)\]
