Question

Can any math nerd help dumb this down for me >~< https://prnt.sc/ku1t6v

Answer 1

Just flip the \(9b^5\) maybe that clears it out

\(9b^5(2b^2-7b^4+4)\)

Answer 2

\(9b^5(2b^2-7b^4+4)\)
=>\(\color{red}{9b^5}(\color{Teal}{2b^2}\color{Green}{-7b^4}\color{Purple}{+4})\)
=>\(\color{red}{9b^5}\times\color{teal}{2b^2}~~~+~~\color{red}{9b^5}\times\color{Green}{-7b^4}~~~+~~\color{red}{9b^5}\times \color{purple}{+4})\)
So for le first part do 9 times 2 and then just add the exponents
\(\boxed{\color{teal}{18b^7}}\)
For the second part same thing \(9\times -7\) and add the exponents
\(\boxed{\color{green}{-63b^9}}\)
For the third, multiply 9 and 4 and just bring down the \(b^5\)
\(\boxed{\color{purple}{36b^5}}\)


\(\bf {18b^7-63b^9+36b^5}\), reorganize it so the biggest exponent goes first:

\(18b^\color{redd}{7}-63b^\color{red}{9}+36b^\color{red}{5}\)

=>Final: \(\bf -63b^9+18b^7+36b^5\) (bold version is also fine though)

Answer 3

Got it ^_^, thank you fer de help >~< I owe you me life
