Answer:
The answer will be 1/9
Step-by-step explanation:
any non zero expression will always be 1. you now have evaluate the powe (-3)^2 which will be 9. Answer should be 1/9. Good Luck!
Answer:
![4 \sqrt{2}](https://tex.z-dn.net/?f=4%20%5Csqrt%7B2%7D)
Step-by-step explanation:
Rewrite 32 as the product of 16 and 2:
![\implies \sqrt{32}=\sqrt{16 \cdot 2](https://tex.z-dn.net/?f=%5Cimplies%20%5Csqrt%7B32%7D%3D%5Csqrt%7B16%20%5Ccdot%202)
Apply exponent rule ![\sqrt{a \cdot b}=\sqrt{a}\sqrt{b}](https://tex.z-dn.net/?f=%5Csqrt%7Ba%20%5Ccdot%20b%7D%3D%5Csqrt%7Ba%7D%5Csqrt%7Bb%7D)
![\implies \sqrt{16 \cdot 2}=\sqrt{16}\sqrt{2}](https://tex.z-dn.net/?f=%5Cimplies%20%5Csqrt%7B16%20%5Ccdot%202%7D%3D%5Csqrt%7B16%7D%5Csqrt%7B2%7D)
Rewrite 16 as 4²:
![\implies \sqrt{16}\sqrt{2}=\sqrt{4^2}\sqrt{2}](https://tex.z-dn.net/?f=%5Cimplies%20%5Csqrt%7B16%7D%5Csqrt%7B2%7D%3D%5Csqrt%7B4%5E2%7D%5Csqrt%7B2%7D)
Apply exponent rule ![\sqrt{a^2}=a](https://tex.z-dn.net/?f=%5Csqrt%7Ba%5E2%7D%3Da)
![\implies \sqrt{4^2}\sqrt{2}=4 \sqrt{2}](https://tex.z-dn.net/?f=%5Cimplies%20%5Csqrt%7B4%5E2%7D%5Csqrt%7B2%7D%3D4%20%5Csqrt%7B2%7D)
I’m pretty sure there are infinite solutions as the system of equations are equivalent to each other.
80.75 / 8.50 = 9.5

Answer:
x³-2x²-4x+8
Step-by-step explanation:
a1=x+2
a2=x²-4⇒q=a2/a1=x-2
⇒a3=q.a2=(x-2).(x²-4)=x³-2x²-4x+8
