Step-by-step explanation:
hope it is helpful to you
you have to apply this formula (a+b)(c-d)=ac-ad+bc-bd
-6a^3*b*5a^2+6a^3b*2ab+6a^3b*b+2ab^2*5a^2-2ab^2*2ab-2ab^2*b=
-30a^5*b+12a^4b^2+6a^3b^2+10a^3b^2-4a^2b^3-2ab^3
The value of the 2 in the hundreds place is 200.
The value of the 2 in the ones place is 2.
Hope it helped! :)
