how do you do this????????
how do u do this problem wuts the aswer i dont get it
its simplifying fractions
4x2, but 2 is a power to x then this is the rest of the problem y theres a line under that problem n the other part of the problem is under it
so 14xy and then the 2 as a power again
(4x^2*y)/14xy .......ok, so we have an x^2 in the top and an x in the bottom, so we can cancel the x in the bottom by dividing it into the x^2 in the top. also, we have a y in the bottom that will cancel completely with the y in the top. 4 and 14 are both divisible by 2, so we can divide a 2 out of the top and bottom which will cancel. so yeah, that was confusing, its really hard to describe the process in words, well not really, but for me right now it is. to make it easier, you can split up the problem so that like variables are together. so here goes:
= 4/14 * x^2/x * y/y
= 2/7 * x * 1 ........now recombine
or you can think of it this way. when we divide two nimbers having the same base, we subtract the powers of the one at the bottom from the one at the top.
so x^m / x^n = x^(m - n)
similarly, x^2 / x = x^(2 - 1) = x^1 = x
and that's why the x^2 in the top cancels the x in the bottom and loses one power. the y in the top has the same power as the y in the bottom, so we are dividing a number by itself, so that piece is just 1. and i think you can simplify 4/14 on your own. so we just kind of put those answers together and we're done in one step
(4x^2*y)/14xy = 2x/7
