nottim · Answer

can you show me your work that you've done? Preferably a picture, if you can. Equation editor too, but that would take a lot of time.

$$3x ^{2}y ^{8}\times7x ^{5}y ^{-4}$$
$$(x+4)^{2}$$

triciaal · Answer

to multiply numbers/variables with the same base add the exponents
to divide numbers/variables with the same base subtract the exponents
remember multiplication and division are opposite pairs like addition and subtraction

triciaal · Answer

you cannot do anything with unlike terms or bases

triciaal · Answer

rearrange to put like bases next to each other to see what you are working with then do the necessary operation

triciaal · Answer

here you are multiplying polynomials so find the base and add the exponents
