1. ## plz can u help me wiv dis question.look inside 2 c wot it is

what is 15x4X20x12/12x7

da 4 is supposed 2 be squared but a 4, n where it says 20x12 da 12 is supposed 2 b squared but a 12 n lastly where it says 12x7, da 7 is supposed 2 be squared but a 7

da big X is supposed 2 b times n da little x is supposed 2 b in algebra wen u get da 2 c's bak 2 bak

plz help, i dno wot da ansa is!!! n i need 2 do it quikly.

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 $\frac {x^a}{x^b} = x^{a - b}$
