Step-by-step explanation:
700070.07 = 700000 + 70 + 0.07
700000 = 7*10^5
70 =7*10^1
0.07=7*10^-2
The answer 19 because, 19+8=27, then 27 divided by 9 is equal to 3. If you need to know how I got 19 just let me know!
To solve this problem you must apply the proccedure shown below:
1. You have the following rational expressions given in the problem above:
[(x+2)/(2x+7)]/ [(x^4)/(x-2)]
2. Then, you have:
(x+2)(x-2)/x^4(2x+7)
3. When you apply the distributive, property, you obtain:
(x^2-4)/(2x^5+4x^4)
4. Therefore, as you can see, the answer is: (x^2-4)/(2x^5+4x^4)
