Yes most of the mathisfun pages are fantastic.
Thanks, Melody....that IS a good site...I even rely on it from time-to-time...!!!
It is hard to think when the question is vague.
Can you give us an exact example and we can talk you through it?
this site has got lots of links that you might find useful
There are a lot of other sites available on the net as well.
We can't raise any positive number to a power (exponent) and expect a negative value in return.
In other words, 8^t can never be negative (or 0).....thus "t" is undefined....
Perhaps this will help

Thanks, guys.....Hey, "Anonymous"....why don't you register???....it's painless !!!
"B" is the correct answer......do you see why??
Me to u guys have help me a lot thx. (>*-*)>u guys awsome<(*-*<)
A percentage is just a number out of 100. To change a percentage to a decimal, move your decimal point over twice to make .0325

np m8
-847288609443

move the decimal 2 to the left.
.124
The probability is given by
nCr(10, 6)*(1/8)^6*(7/8)^4 +
nCr(10, 7)*(1/8)^7*(7/8)^3 +
nCr(10, 8)*(1/8)^8*(7/8)^2 +
nCr(10, 9)*(1/8)^9*(7/8) +
(1/8)^10
= about 0.00051 = about .051%
7 1/3
like 4x + 9= 12x?
2x-3(5/3 - x/3)=-17 distribute the -3 across the terms in the parentheses
2x - 5 + x = -17 simplify
3x - 5 = -17 add 5 to both sides
3x = -12 divide by 3 on both sides
x = -4
Take a look at this

whats 2ab plus -9b
They are unlike terms so you cannot put them together with plus or minus
2ab + - 9b
Minus numbers or terms are 'cold'
so here you are adding cold so the room will gett colder. So + - is replaced with a -
=2ab - 9b
If x = 53 -y, then the first equation, x + y = 53, becomes
(53 - y) + y = 53
53 = 53
And there is nothing to solve....
Hit the "2nd" button...you will see "asin" "acos' "atan"
Approximately 1746.031214
The EXACT value is ±(4√484).....there is nothing more we can do....
i meant the exact value. sorry bout that. tkns for the answers i got could someone please tell me the exact value like with a reciprical bar or whatever that is called with the square roots. Thanks again so much i just got this asignment and dont understand.
4x-y+3=0 add y, subtract 3 from both sides
4x = y - 3 divide both sides by 4
x = [ y - 3 ] / 4
