For this case we must indicate the value of the following expression, expressed in scientific notation:
![(1.2 * 10^{-3}) * (1.1 * 10^{8}) =](https://tex.z-dn.net/?f=%281.2%20%2A%2010%5E%7B-3%7D%29%20%2A%20%281.1%20%2A%2010%5E%7B8%7D%29%20%3D)
We have that for multiplication properties of powers of the same base, the same base is placed and the exponents are added:
![a ^ n * a ^ m = a ^ {n + m}](https://tex.z-dn.net/?f=a%20%5E%20n%20%2A%20a%20%5E%20m%20%3D%20a%20%5E%20%7Bn%20%2B%20m%7D)
Then, rewriting the expression we have:
![(1.2 * 1.1) * 10 ^{- 3 + 8} =\\1.32 * 10 ^ 5](https://tex.z-dn.net/?f=%281.2%20%2A%201.1%29%20%2A%2010%20%5E%7B-%203%20%2B%208%7D%20%3D%5C%5C1.32%20%2A%2010%20%5E%205)
Answer:
![1.32 * 10 ^ 5](https://tex.z-dn.net/?f=1.32%20%2A%2010%20%5E%205)
The answer is B(2,22).

![x = 30 \\ y = 10](https://tex.z-dn.net/?f=x%20%3D%2030%20%5C%5C%20y%20%3D%2010)
Step-by-step explanation:
![8x + 6y = 300 \\ x + y = 40 \\ 6x + 6y = 240 \\ 2x = 60 \\ = > x = 30 \\ y = 10](https://tex.z-dn.net/?f=8x%20%2B%206y%20%3D%20300%20%5C%5C%20x%20%2B%20y%20%3D%2040%20%5C%5C%206x%20%2B%206y%20%3D%20240%20%5C%5C%202x%20%3D%2060%20%20%20%5C%5C%20%3D%20%20%3E%20x%20%3D%2030%20%5C%5C%20y%20%3D%2010)
