X is 10^10. under the log there is "10", but we don't write it if this number is 10. You cross that under Y. Replace the "Y" with "10".

How do you figure this stuff

I don't know about American Education System but I can say that Turkish Education System is rough.

This is hard but I asked my dad and he figured it out but he had to use a calculator a little. Every month, a girl gets allowance. Assume last year she had no money, and kept it up to now. Then she spends 1/2 of her money on clothes, then 1/3 of the remaining money on games, and then 1/4 of the remaining money on toys. After she bought all of that, she had \$7777 left. Assuming she only gets money by allowance, how much money does she earn every month?

I hope I get the question right(You know, I am not solving math questions in English, because of that this comes to me a little bit strange). Let's solve. She spent her money to clothes, she has 1/2 of her money left. Then she spends "the remaining money" on games. So "x" 1/2 with 1/3 = 1/6. Lets find the total spent. 1/2 at first, now 1/6. "+" = 4/6 = 2/3. Now lets find remaining money. 1 "-" 2/3 = 1/3. We have to find money spent on toys. 1/4 "x" 1/3 = 1/12. So total spent is 2/3 "+" 1/12 = 9/12. Remaining money 1 "-" 9/12 = 3/12 = 1/4. 1/4 money is 7777\$ . So if we want to find a month, firstly we will find the year, then the month. 7777 "x" 4 ":" 12 = is your answer.

Nope it's \$2222 try again.

Because of solving it from my mind while writing in english, yes I did mistake.(And also it was 02.00(night) in Turkey so I was sleepy too. I will try again now. But this time we wont get lost with the "/" things. I know a shortcut maybe you know this too. 1/2, 1/3 and 1/4. 2,3,4 the smallest same number is 12(I mean you can divide it to 2,3 and 4). Lets say to the girls money 12y. She spent 6y to the clothes(1/2), 6y left. She spent 2y to games, 4y left(1/3). She spent 1y to toys(1/4) Total spent 9y. 3y left. 3y is 7777 dollar. so 12y is 7777x3 for one mont it is 7777/4 (I am not finding the same answer with you maybe you could have written the question wrong, or maybe english is not my native lang. I could have understand the question wrong sorry)

10^10 = 10,000,000,000

I thought it was 10

My answer is the same as immobilizersystem's. He said
x = 10^10 which = 10,000,000,000.
Look at the first line of his answer.
Here's how:
y = log x, with y = 10
means log x = 10
means 10^10 = x
so 10,000,000,000 = x
