    x = 35

    Step-by-step explanation:

    27 = 3^3

    so now it would be (3^3) ^x+10, you multiply the exponents and get 3^3x+30

    so now you have two bases that have a 3, by rule, if you have the same bases your exponents should be the same, so you just equal the other exponent which is 4x-5

    so 4x - 5 = 3x + 30

    4x - 3x = 30 + 5

    x = 35
