# utterly useless contest :\

well i forgot to do my homework, and can't find my calculator. so im asking you guys to help me.
they're all very easy, but i'm not in the mood right now (busted 3 times in NFSMW)

25^3 * 25^2 + 10^10 =
10^6 : 10^2 =
8^7 : 8^5=
7^3 : 7^2=
4^5 : 4^3=
9^7 : 9^6=
5^4 : 5^2=
8^7 : 8^7=
(5^3)^5=
(7^2)^2=
(-2^3)^-2=

the ones i need to do ^^
35 frih\$

and if you do this one, i make it 55 (it's a bonus one )
(-2^-3)^3 + (-3^-2)^2 =
mtorregiani
25^3 * 25^2 + 10^10 = 25^5 + 10^10 = ~ 1.001x10^10
10^6 : 10^2 = 10^4
8^7 : 8^5 = 8^2 = 64
7^3 : 7^2 = 7^1 = 7
4^5 : 4^3 = 4^2 = 16
9^7 : 9^6 = 9^1 = 9
5^4 : 5^2 = 5^2 = 25
8^7 : 8^7 = 1
(5^3)^5 = 5^15 = ~ 3.05x10^10
(7^2)^2 = 7^4 = 2401
(-2^3)^-2 = -2^(-6) = 1/60

You don't need a calculator for most of them.

now comes the bad news :\
i need exact anwsers, so fully, all decimals and all digits...

raised reward to 75 frih\$ btw

What do you mean..?

yea, but i think you made some mistakes ^^ not sure..
Gushe
Idk, I just put them in my calculator (CASIO fx-92 scientific calculator) and that is what I got

ah ok, 75 frih\$ for you ^^

don't you think these are exact enough? Everything except for the bonus was already done here and with exact answers which 0.015625 or 0.010392554 aren't.

I agree with rvec, mtorregiani gave you the right answers before Gushe (excluding the bonus question).

 endless wrote: i need exact anwsers, so fully, all decimals and all digits...

If the questions themselves were meant to be in exact answers then what mtorregiani gave you was fine. For example 1/3 is more accurate than 0.333, a fraction is a rational or exact number. The same as a surd. Often writing something like 7^8 : 7^5 as 7^3 will suffice, it depends on the wording of the question. I hope you know the rules of indices yourself!

like i said, the book said that if the awnser was calculateable (or something like that) you also need to calculate that ^^
mtorregiani
It's ok mates (rvec & ninjakannon), thanks for your support.

You should have done the rules a little bit more clear
Gushe
I donated mtorregiani the half of the gained Frih\$, because I think that's the most fair, isn't it?

~Gushe

By the way folks if an accurate answer is required then you can only use fractions. BTW -2^(-6) = 1/64 not 1/60. Havn't checked any more but this stuck out like a sore thumb.

Doesn't anybody else find it ethically wrong to have done someone's homework for him?
I don't mind someone asking for HELP with homework, where you can explain to them how to do it, but to actually do the homework?
endless
i can do it myself, but im too lazy ^^ i had 9.9 at my (booklet with grades or something)

It's probably more effort to ask here though isn't it. You still have to write it up afterwards and spend time on the forums talking about it. Silly idea really?
tidruG
ninja has a point, you know
endless
nah, i was just too lazy to think about them ^^

I don't mind, the one that would have problems at Math is not me
And sorry for that mistake at the last question, it was my fault.
