numbers in ^^ are powers. eg. 2^6x is two to the power of six minus x.
simplify: 2^(n+2) times 6^(n4) over (12)^(n1)
solve for x 2(9)^(2x1)  5(3)^(2x) + 18 = 0
solve for x 2(25)^(x+1) + 5^(x+2)  3 = 0
solve for x and y 5^(x2y+1) = 25^(x2y) and 4^(xy+2) = 32^(x2y+1)
find the coefficient of x^5 in the expansion of (2x+3)(x2)^6
thanks, if u only want to answer one question that is still GREAT. i jst totally failed my test and really need to know the answers to what i did wrong, cause theres a remed this week. thanks!!
