    when you mulitplyc same bases you should add their exponents exxample \[\huge\rm x^m \times x^n = x^{m+n}\]

    9? to the 9 power ? multiply coefficient (7 times 2)(n^4 times x^5)

    nope 9 is right bec you have to add exponents so n^9 not 14^9

    okay so it would be 14n^9

    \[\huge\rm (7 \times 2)(n^4 \times n^5)=(7 \times 2) n^{4+5}\]

    that's same like we just did multiply coefficients and add exponents of variables

    x is same as x to the one power x=x^1

    so it would be like -15^xy13? or -15x^5y8

    add coefficient of same variables you can't add 3 exponent of y with 5 exponent of x x^{1+4}
