Best ResponseYou've already chosen the best response.3you can use pascal's triangle for the coefficient and the exponent of first term start from highest degree to 0 and the exponent of 2nd term start from 0 to highest degree dw:1443580070541:dw like in this example power of first term is decreasing and 2nd term exponents are increasing

Best ResponseYou've already chosen the best response.0So in this case, you would use the third row of pascal's triangle? Since it's to the third power?

Best ResponseYou've already chosen the best response.0I'm still kind of confused... do you multiply the coefficients of the binomial's terms (that are being raised to a certain power), by the numbers of the specified Pascal's Triangle row?

Best ResponseYou've already chosen the best response.3yes in ur question there are numbers in first and term so you should multiply the coefficient by the coefficient of the term dw:1443581219197:dw now u should multiply the coefficient one by 5^3

Best ResponseYou've already chosen the best response.3\[\large \rm (5x5y)^3=\color{ReD}{1}(5x)^\color{blue}{3}(5y)^0+\color{reD}{3}(5x)^\color{blue}{2}(5y)^1.......+\] as u can see power of first term is decreasing andexponent of 2nd terms is increasing
