Answer:
x^4- x^3- 4x^2-3
Step-by-step explanation:
Given
f(x)= x^4- x^2+9
And
g(x)= x^(3 )+ 3x^2+12
We have to find
(f-g)(x)= ?
The operations on functions are as easy as the operations on numbers or polynomials.
We have to subtract the functions to find the above mentioned operation.
=(f-g)(x)=f(x)-g(x)
(f-g)(x)=[x^4- x^2+9]-[x^(3 )+ 3x^2+12]
The minus will change the signs of function g.
= x^4- x^2+9- x^(3 )- 3x^2-12
= x^4- x^3- x^2- 3x^2+9-12
=x^4- x^3- 4x^2-3
Well not sure what you are asking, but If it is what I think it is, it would go like this:
2
(9^2)
Then the answer should be
9^4 since we multiply the exponents.
If you mean this...
3^2....It would be same as 3 x 3 which we should know is equal to nine.
Hope I helped! (Be sure to thank me!)
Answer:
The simplified value of 
is 
.
Step-by-step explanation:
As the given expression is
Lets simplify this expression step by step
As
![-25^{-\frac{1}{2}}....[A]](https://tex.z-dn.net/?f=-25%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D....%5BA%5D)
So, lets plug in equation [A] i.e.
∵
∵ 
Therefore, the simplified value of is .
