Well, you are subtracting g(x) from f(x) so:
√x-x-(2x^3-√x-x) which is:
√x-x-2x^3+√x+x (you have your signs wrong at the bottom of your post)
Now you would simply combine like terms (do your addition and subtraction of like terms)
-2x^3+2√x
So the answer is D.
<span>The integer subtraction is goverend by the following the simple rules that the subtarction is normal as the natural numbers but the sign of bigger number comes in the final result. For example: -47 is to be subtracted from + 50 then, result = 50-47 = +3. But, see another example, If -7 is to be subtracted form -8 then , we will write as -8 -(-6) = -8 + 6 = -2. These rules are followed : (-)(-) = + and (-)(+) = - and (+)(+) = +</span>
Answer:
Step-by-step explanation:
The volume of a cube is given by the formula :
a³ (where a is the side length )
So now we have to cube these lengths :
Part A :
(3x²y)³ =
(3x²y)(3x²y)(3x²y) =
(9x^4y²)(3x²y) =
27x^6y³ (This is now fully simplified so our final answer for a)
Part B:
(5y²)³ =
(5y²)(5y²)(5y²) =
(25y^4)(5y²) =
125y^6 (This is now fully simplified so our final answer for b)
Hope this helped and have a good day
