    this is good practice for me. so anyway we are using all 3 exponent rules together.

    log rules \[\log (mn) =\log(m)+\log(n)\] \[\log (\frac{m}{n}) =\log(m)-\log(n)\] \[\log (m^n) =n \cdot \log(m)\]

    ok I know for sure that exponent rule for logs is being used... so is the second rule for subtraction

    would (x+3)^2 be 2log(x+3)

    yeah that's good |dw:1438054541907:dw| so now we need to use the subtraction rule for the remainder of the problem . I see fraction s

    2log(x+3)-(x-2)(x^2+5)^4?

    close but we are missing something. we are missing the - sign and the logs also by exponent rule that 4 should be to the left.

    log expansions should always have a + or - sign depending on the log rules. In this one, we are dealing with the subtraction... yeah that looks good
