## anonymous 5 years ago have a hard time with math all together. I question is w=C * 3,963square -2

1. anonymous

Is the equation: a) $$w = C * 3963^2 -2$$ b) $$w = C * 3963^{-2}$$ c) $$w = (C * 3963)^2 -2$$ d) $$w = (C * 3963)^{-2}$$ e) None of the above?

D

Ok, so First thing to simplify is to distribute that exponent. $(a^1*b^1)^c = a^{1*c} * b^{1*c}$

Polpak popcorn is back whenever you get time. :-)

$$C = C^1$$ and $$3963 = 3963^1$$ right?

6. anonymous

Shouldn't have used c in my example. But the point being you multiply the exponents.

7. anonymous

So what does your expression simplify to when you distribute the -2 exponent?

8. anonymous

does the negatuve exponent change or stay the same

9. anonymous

thank you

my problem now is D=1.2$\sqrt{h}$
