Answer 1

Answer:

(36a2−72ab−15a+36b2+10b

Step-by-step explanation:

1. (8 • ((3a - 3b)2)) - 10 • (3a

Simplify ( 3a-3b )2

Put the exponent aside and simplfy the base by pulling out like factors :

 3a-3b  =  3 • (a-b) 

Remember the 4th law of exponents : (a • b)m= am• bm

Retract the exponent and apply the 4th law to the simplified base: ( 3 • (a-b) )2 =  (3)2 • (a-b)2  

(23•32) • (a - b)2 - 10 • (3a - 2b)

=Evaluate :  (a-b)2   =

Pull out like factors :

   72a2 - 144ab - 30a + 72b2 + 20b  = 

  2 • (36a2 - 72ab - 15a + 36b2 + 10b)

Final result :

2 • (36a2 - 72ab - 15a + 36b2 +
