    do you mean \frac {15x^4 \times 20x^{12}}{12x^7}?

    speak english please, this is a prestigious forum. it's bad enough that people like me don't capitalize what we should.

    when multiplying you can multiply in any order, so here's how to approach this

    \frac {15 x^4 \times 20x^{12}}{12 x^7} = \frac {15 \times 20 \times x^4 \times x^{12}}{12 x^7}

    = \frac {5 \times 5 \times x^{16}}{x^7} ..........since x^a \times x^b = x^{a + b}

    = 25 \frac {x^{16}}{x^7}

    = 25 x^9 ...............since \frac {x^a}{x^b} = x^{a - b}
