Answer: tan(14x)
<u>Step-by-step explanation:</u>
Consider the Sum Formula for tan:
![tan(A + B)=\dfrac{tan(A)+tan(B)}{1-tan(A)(tan(B)}\\\\\\tan(9x+5x)=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}\\\\\\\large\boxed{tan(14x)}=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}](https://tex.z-dn.net/?f=tan%28A%20%2B%20B%29%3D%5Cdfrac%7Btan%28A%29%2Btan%28B%29%7D%7B1-tan%28A%29%28tan%28B%29%7D%5C%5C%5C%5C%5C%5Ctan%289x%2B5x%29%3D%5Cdfrac%7Btan%289x%29%2Btan%285x%29%7D%7B1-tan%289x%29%28tan%285x%29%7D%5C%5C%5C%5C%5C%5C%5Clarge%5Cboxed%7Btan%2814x%29%7D%3D%5Cdfrac%7Btan%289x%29%2Btan%285x%29%7D%7B1-tan%289x%29%28tan%285x%29%7D)

Answer:
4) x^10
Step-by-step explanation:
1) If two numbers have the same base (i.e. x^3 and x^4) and you are multiplying them you just add the exponents. Therefore x^3*x^4 would be x^(3+4) which equals x^7.
2) When dividing similar bases you have to subtract the exponents. If we have x^18÷x^8 that is equivalent to x^(18-8) which gives us x^10.
3) If we have (x^3)^3 we will need to multiply the exponents. Therefore (x^3)^3 is equivalent to x^(3*3) which gives us x^9.
4) (x^2*x^4)^4÷x^8
First do what's in the parentheses,
(x^2*x^4) = x^6
Next do the exponents,
(x^6)^3 = x^18
Lastly the division,
x^18÷x^8 = x^10
x^10 is our answer.
