Question: the figer in&out parentheses

After multipication,I got some [  ],like these

(1.388888889*10^(-7)*omega^4+3.429355280*10^50-1.000000000*10^(-36)*omega^6-1.543209877*10^22*omega^2)*bbbb^3+(1.924500898*10^5*omega^2*[-5.702224882*10^14*bbbb]+[4.064421073*10^48*bbbb]+1.666666666*10^5*omega^2*[-3.292181070*10^14*bbbb]-2.000000000*10^(-24)*[-3.292181070*10^14*bbbb]*omega^4)*bbbb^2+(2.777777776*10^16*[-5.702224882*10^14*bbbb]^2-1.000000000*10^(-12)*omega^2*[-5.702224882*10^14*bbbb]^2-1.000000000*10^(-12)*omega^2*[-3.292181070*10^14*bbbb]^2+2.777777776*10^16*[-3.292181070*10^14*bbbb]^2)*bbbb

I donot want to get the [ ],and I hope the figers outside the parenthese really multipicate the figers inside the parenthese.And then obtain the colletion of the similar terms.

What should I do ,thank you
