Answer:
6554
Step-by-step explanation:
The sequence 2, -8, 32, -128 has a first term (a1) of 2 and a common ratio (r) of -8/2 = -4. The sum of n terms is given by ...
Sn = a1·(r^n -1)/(r -1)
For your sequence, the sum of 7 terms is ...
S7 = 2·((-4)^7 -1)/(-4-1) = 2(-16384/-5) = 6554
The sum of changes after the 7th day is 6554.

Answer:
$$\sqrt[3]{27x^6y^4}=3 x^2\sqrt[3]{y^4}$$
Step-by-step explanation:
![\sqrt[3]{27x^6y^4}= \sqrt[3]{3^3x^6y^4}\\\sqrt[3]{27x^6y^4}=\sqrt[3]{3^3} \sqrt[3]{x^6} \sqrt[3]{y^4}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27x%5E6y%5E4%7D%3D%20%5Csqrt%5B3%5D%7B3%5E3x%5E6y%5E4%7D%5C%5C%5Csqrt%5B3%5D%7B27x%5E6y%5E4%7D%3D%5Csqrt%5B3%5D%7B3%5E3%7D%20%5Csqrt%5B3%5D%7Bx%5E6%7D%20%5Csqrt%5B3%5D%7By%5E4%7D)
therefore,
![\sqrt[3]{27x^6y^4}=3 x^2\sqrt[3]{y^4}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27x%5E6y%5E4%7D%3D3%20x%5E2%5Csqrt%5B3%5D%7By%5E4%7D)
