Answer:
1*10^2
Step-by-step explanation:
In general the binomial expansion is

So in our case, because we want ascending powers of x we'll write,

We need to calculate the binomial coefficients:






Answer: 820,000
823,563 rounded to the nearest ten thousand is 820,000
Y = 1 and x = 10
To solve this you cancel out the x's and get -8y=-8.
You find y as 1, plug it back into the equation to get 2x-5=15. Solve and get x=10.
