    Simplify the expression into positive exponents

    [ (2m^2p^3)^2 * (4m^2p)^-2 ] / [ (-3mp^4)^-1 * (2m^3p^4)^3 ] i worked it out on my own and got the answer 3/32m^8p^4 can someone please work it out and confirm if u used the right process? many thanks.

    simplify radicals with exponents

    I had a real hard time with this problem and ended up getting it wrong, can someone point me in the right direction on how to solve it? (√y^5)/(3^√y^7) (note, by 3^√ I mean y^7 cubed) The answer should have been: 6^√y Attached an image to help make my question more clear. Thanks...

    Problem With Variable Exponents

    Hey guys, I've been working on some math and have hit a cement wall containing bits of broken glass. Allow me to give you the gist of it. Here is the problem: (x-2)(x-3)(x-4)2^X=0. Now I have found the following answers {2, 3, 4, and undefined}. What I was wondering is because one of the values...

    Please help with difference of logarithms

    Please help me with this problem. I've tried at least 6 different methods to solve it and they've ALL been wrong. I'm wasting too much time on this problem. Here it is: log5(x+1) - log4(x-2) = 1 Where log5 and log4 are log base 5 and log base 4, respectively. I have tried converting to...

    Exponents

    1. Given that 2^a = 3^b = 18^c, Show that ab=c(b+2a). 2. Given that p^1/2 - p^(-1/2) = 2, Show that p + p^(-1) = 6

    Negative Exponents

    Consider the following: 7/x^-^5^/^6 To express the above with a positive index i.e. to make the the exponent -5/6 positive, we need to do the reciprocal which will be 1/7/x^-^5^/^6 which comes to x^5^/^6/7 But the correct answer is 7x^5^/^6 Why? Thanks, Ron

    how to solve equations with variables as exponents?

    What steps would I have to do to solve an equation such as 2 x 3 = 7 x 5^x and 4.6 x 1.06^(2x + 3) = 5 x 3^x if you could answer in the simplest way you can it would be greatly appreciated. :)
