10^x/10000000=100000 solve x
Answers
Step-by-step explanation:
10000000/x=100/1
(10000000/x)*x=(100/1)*x - we multiply both sides of the equation by x
10000000=100*x - we divide both sides of the equation by (100) to get x
10000000/100=x
100000=x
x=100000
now we have:
1% of 10000000=100000
Answer:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
1000000-((n*(n+1))/2)=0

Rewriting the whole as an Equivalent Fraction
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 2 as the denominator :
1000000 1000000 • 2
1000000 = ——————— = ———————————

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
1000000 • 2 - (n • (n+1)) -n2 - n + 2000000

Pulling out like terms :
4.1 Pull out like factors :
-n2 - n + 2000000 = -1 • (n2 + n - 2000000)
Trying to factor by splitting the middle term
4.2 Factoring n2 + n - 2000000
The first term is, n2 its coefficient is 1 .
The middle term is, +n its coefficient is 1 .
The last term, "the constant", is -2000000
Step-1 : Multiply the coefficient of the first term by the constant 1 • -2000000 = -2000000
Step-2 : Find two factors of -2000000 whose sum equals the coefficient of the middle term, which is 1 .
