Answer:
When you add a negative and positive your answer would always be a negative.
Step-by-step explanation:
Answer:
6^5 * 9^5
Step-by-step explanation:
( 6*9) ^5
We know that ( ab) ^c = a^ c* b^c
6^5 * 9^5
We are given
![((2x^9)(y^n))((4x^2)(y^{10}))=(8x^{11})(y^{20})](https://tex.z-dn.net/?f=%28%282x%5E9%29%28y%5En%29%29%28%284x%5E2%29%28y%5E%7B10%7D%29%29%3D%288x%5E%7B11%7D%29%28y%5E%7B20%7D%29)
Firstly, we simplify left side
Left side is
![((2x^9)(y^n))((4x^2)(y^{10}))](https://tex.z-dn.net/?f=%28%282x%5E9%29%28y%5En%29%29%28%284x%5E2%29%28y%5E%7B10%7D%29%29)
we will make all x terms together
and y terms together
![(2x^9)(4x^2)(y^n)(y^{10})](https://tex.z-dn.net/?f=%282x%5E9%29%284x%5E2%29%28y%5En%29%28y%5E%7B10%7D%29)
![2\times 4(x^9)(x^2)(y^n)(y^{10})](https://tex.z-dn.net/?f=2%5Ctimes%204%28x%5E9%29%28x%5E2%29%28y%5En%29%28y%5E%7B10%7D%29)
![8(x^9)(x^2)(y^n)(y^{10})](https://tex.z-dn.net/?f=8%28x%5E9%29%28x%5E2%29%28y%5En%29%28y%5E%7B10%7D%29)
we can multiply left side by using exponent rule
![a^m\times a^n=a^{m+n}](https://tex.z-dn.net/?f=a%5Em%5Ctimes%20a%5En%3Da%5E%7Bm%2Bn%7D)
![8(x^{9+2})(y^{n+10})](https://tex.z-dn.net/?f=8%28x%5E%7B9%2B2%7D%29%28y%5E%7Bn%2B10%7D%29)
![8(x^{11})(y^{n+10})](https://tex.z-dn.net/?f=8%28x%5E%7B11%7D%29%28y%5E%7Bn%2B10%7D%29)
now, we can set them equal
![(8x^{11})(y^{n+10})=(8x^{11})(y^{20})](https://tex.z-dn.net/?f=%288x%5E%7B11%7D%29%28y%5E%7Bn%2B10%7D%29%3D%288x%5E%7B11%7D%29%28y%5E%7B20%7D%29)
Since, both sides have x,y and 8
and both are equal
so, their exponent must be equal
so, exponent of y must also be equal
we get
![n+10=20](https://tex.z-dn.net/?f=n%2B10%3D20)
