[quote=CowPoop]((5^702)-(5^700)+24)/(5^700)+1 = 25
((5^702)-(5^700)+24)/[(5^700)+1] = 24[/quote]

This is the solution.

(5^2+24)/(5^700)
(25+24)/(5^700)
49/5^700
Are you sure those are ^ and not multiplications

Lemme try this again i failed right there
((5^702)-(5^700)+24)/(5^700)
I give up 9th grade is algebra for me

Well no idea how to make the link work, but that website is your answer. O_O

If you simplify it, you don't even have to do any long calculations. The answer should be 24, or atleast thats what I got.

BTW for all those who say you can factor it out. I don't think you can factor anything out if it's add or subtract
If you simplify, it'd look like this

(5^702)/(5^700+1) - (5^700)/(5^700+1) + (24/5^700+1)

Mind Blown.

Good thing I don't have math this year

you want divided by (5^700+1) or divide by (5^700) then the quotient added by 1?

@iFrancisco: Woah, I really should learn how to notice these little stuff.
Probably why I'm failing math (and the fact that there are way too many formulas to remember).

EDIT:
How does the 5^700-5^700 turn into -1?

[quote=iFrancisco]If this is the question...

=>((5^702)-(5^700)+24)/(5^700)+1
=>[(5^2-1)*(5^700)+24]/(5^700) + 1
=> [24*5^700+24]/(5^700) + 1

By use of limits and approximation, => 24*1+1 = 25. This is because (5^700+24)/(5^700) is practically 1, as the difference is extremely small and for all purposes the same as 1.[/quote]

How'd the 5^702 turn into 5^2-1?
Please answer without sarcasm.

*whoops neglected that +24... So yea. Im wrong

((5^702)-(5^700)+24)/(5^700)+1 = 25
((5^702)-(5^700)+24)/[(5^700)+1] = 24

[quote=shadowthedark]Woah, really? Well, I'm going to give you a radical idea...break it up into parts. Now hold on because this idea comes from 12th grade math. Now, you're going to solve one part of the problem first. Such as 5^702. Then once you have the answer to that one...write it on scratch paper. You know what scratch paper is right? Then, solve the next exponent. Once you've got that down, you can take your two answers and subtract them and add 24. You following me so far? Now write down your final answer and then, do the same thing to the divisor(the one at the bottom) and repeat the process. Once you have your final answers, divide the dividend by the divisor and you should get the right answer.[/quote]

Really, thanks! You're one big idiot. Come back when you answered 5^702 on a calculator. The number is too large to fit you smartarse.
And yeah, the answer was 24.

You can't add/substract powers unless you remove the exponent. So grab a calculator, type it out, and you're done.

[quote=Bill897]It's 24.
(5^702-5^700+24)/(5^700+1)
= (5^700(5^2-1)+24)/(5^700+1)
= (24(5^700)+24)/(5^700+1)
= (24(5^700+1))/(5^700+1)
= 24[/quote]

Thanks, yours looks right.

I did it like this.
(5^702)-(5^700)+24/(5^700)+1
=5^700(5^2-1)+24/(5^700)+1
=(5^2-1)+24/1+1
=24+24/1+1
=48/2
=24

Shouldn't you have a scientific calculator by grade 8 or something? You can fit the longest equation in those things.
I even used the available letters to make words.

5^702-5^700+24/5^700+1 = 24

Or in other words: (5^702)-(5^700+24)/(5^700+1)

Or: (5^702)-(5^700)+24/(5^700)+1

Or: (5^702)-(5^700+24)/(5^700)+1

Or: (5^702)-(5^700)+24/(5^700+1)

You seriously need some parentheses.

5 to the power of 702 is like infinity

Are you sure that's the problem? Parentheses would be helpful.
I don't think 24 is anywhere near the correct answer.
