-6х²у•2у²•15х

To simplify the expression -6х²у•2у²•15х, we can multiply the coefficients and add the exponents of like terms. Let's break it down step by step.

-6 * 2 * 15 = -180 (multiplying the coefficients)

х² * х = х^(2+1) = х³ (adding the exponents)

у * у² = у^(1+2) = у³ (adding the exponents)

Therefore, the simplified expression is -180х³у³.
