DUE TOMORROW AND IM IN TROUBLE...ANY HELP SOOOOO APPRECIATED!
1. the powers of 10 nearest in value to 10^2004, but not equal to it, are 10^a nad 10^b. what is the value of a+b? [NOTE: a power of 10 is an integer of the form 10^n, where n is an integer.]
2. If a^2-b^2 is not = to 0, then, in terms of a and b, what are both solutions of
(a^2-b^2)x^2-(a^2+b^2)x + ab=0?
3. Waht are all values of x that satisfy x(squareroot of x) - 2(square root of x) =x
