How to simplify this

Mathematics
1 answer:
algol [13]3 years ago
6 0
To simplify this, you would have to turn b^-2 into a positive exponent.
To do this, we have to flip b^-2, which would get rid of the negate from the exponent: -2

3a^4 b^-2 c^3 / b^-2

Then we get the answer:

3a^4 c^3
------------
   b^-2

I have a picture to clarify! 
I hope this helped, let me know if you don't understand! ^.^

Find the domain of the function
NeX [460]
For Domain<span>, you just need to watch out for Square Roots and/or Fractions! 1) a POLYNOMIAL (no square roots or fractions), i.e. f(x) = x^2 + 3x + 1, </span>domain<span> is "all real numbers." 2) a FRACTION (w/ no square root), i.e. f(x) = (2x+1)/(x^2+5x+6). Set bottom "not equal" to zero.</span>

What is the smallest positive integer for x so that f(x)=200(2)* is greater than the value of g(x)=500x+400?
Goshia [24]
We have to functions, namely:

f(x)=200(2)^{x} \ and \ g(x)=500x+400

So the problem is asking for the smallest positive integer for x so that f(x) is greater than the value of g(x), that is:

f(x)\ \textgreater \ g(x) \\ \therefore 200(2)^{x}\ \textgreater \ 500x+400

Let's solve this problem by using the trial and error method:

for \ x=1 \\f(1)=400 \\ g(1)=900 \\ Then \ f(1) \ \textless \ g(1) \\ \\ \\ for \ x=2 \\f(2)=800 \\ g(2)=1400\\ Then \ f(2)\ \textless \ g(2) \\ \\ \\ for \ x=3 \\f(3)=1600 \\ g(3)=1900 \\ Then \ f(3)\ \textless \ g(3) \\ \\ \\ for \ x=4 \\f(4)=3200 \\ g(4)=2400 \\ \boxed{Then \ f(4)\ \textgreater \ g(4)}

So starting x from 1 and increasing it in steps of one we find that:

f(x)>g(x)

when x=4

That is, the smallest positive integer for x so that the function f(x) is greater than g(x) is 4.

A fast food restaurant was selling 7 boxes of chicken nuggets for $25.90.
mash [69]
The food with a higher unit price is chicken nuggets because when you multiply 7 and 25.90 you get 181.3. When you multiply 3 and 11.07 you get 33.21. The answer is chicken nuggets.
