Simplify the expression r^-3s^5t^2 divided by r^2st^-2
124012
ok so when u divide  stuff like that, u just subtract the exponents.  \nr^-3 s^5 t^2\n---------------\nr^2 s t^-2\n\nso for the r, the new exponent would be r^(-3-2) = r^-5\nfor the s, s^(5-1) = s^4.  (s by itself is equal to s^1.)\nfor the t, t^(2-[-2]) = t^4\nso the new expression is  r^-5 s^4 t^4. \nand if you really wanted to, u could rewrite r^-5 as 1/r^5. cuz thatz how negative exponents work. (x^-2 = 1/x^2)\nso then the final answer would be s^4t^4/r^5.\nhope this helps. let me know if u need more help

You can factor out 15bc^2\n15bc^2(5b + 4c^4)

I have been able to simplify it till:\n\n358x^2-450x divide 115x^2-130x\n\nYou can discuss if I am not getting the thing and if you need help on my email:\ntalhaiba@yahoo.com

remember that you can add subtract multiply or divide the equation as long as you do the same thing to both sides of the = sign.\n\nStart with 2+5t-3=34  What we want to do is to get the t all alone on one side.\n\nSubtract 2 from each side:\n5t-3=32\n\nAdd 3 to both sides:\n5t=35\n\nDivide both sides by 5:\nt=7\n\nGo back to the original equation and put the 7 where the t was and see if it is correct.\n\nMichael

(a^2 -2ab + b^2) = (a-b)(a-b) = (a-b)^2\nYou cannot cancel anything, so \n(a^2 -2ab + b^2)/(a+b) does not simplify.\n\nYou may wish to write it as (a-b)^2 /(a+b)

It just takes foiling-\n\n(5*2)+(5*5i)+(-3i*2) +(-3i*5i)\n(10)+(25i)+(-6i)+(-15*i^2)\ni^2=-1\nso...\n25+19i\n\nTo those who have said that you can't simplify it past 10 + 19i - 15i^2, that isn't correct considering that since i is the square root of -1, i^2 is -1. That's why you can simplify -15i^2 to 15, thus making it 10+19i+15, or 25+19i
