    3x+26. You distribute the three to all numbers listed in the parenthesis. Like this : 3*x+3*13 Because there is no equal sign, you cannot go further.

    I would say this is much harder than simplification. Here you simply multiply the two numbers, and use some 'laws of indices': \[(6xy^2)(3x^3y) = 18x^{1+3}y^{2+1} = 18x^4y^3\]

    This is the adding of exponents. Imagine there is a 1 on the x and the y with no exponent. Like this : (6x^1y^2)(3x^3y^1) You multiply the numbers before x. In this case, that is 6*3 6*3 = 18. You are also multiplying the exponents. When you multiply an exponent, you add the two exponents together. So : 18x^4 Now, to finish this equation, we must add the exponents of the 'y' Therefore you answer is... y^3. 18x^4y^3
