Answer:

14b - 10ab + 34a²b - 64a²b²

Step-by-step explanation:

We have to simplify the expression

2ab + 3b + 7b + 3a × 3a × b + 4b - 8ab × 8ab + 5a × 5a × b - 12ab

= 2ab + 3b + 7b + 9a²b + 4b - 64a²b² + 25a²b - 12ab

{Since (3a × 3a × b) = 9a²b, (8ab × 8ab) = 64a²b² and (5a × 5a × b) = 25a²b}

= 2ab + 10b + 9a²b + 4b - 64a²b² + 25a²b - 12ab  

= 14b - 10ab + 34a²b - 64a²b² (Answer)

Hello! Expanded form is when you write an addition problem by place value in order to get the sum for the answer. For example, expanded form of 123 is 100 + 20 + 3. In this case, 92.3 is out number we are going to expand in addition form. 92.3 in expanded form is 90 + 2 + 0.3. This is because 9 in the tens place has a value of 90, the 2 in the ones place has a value of 2, and the value of 3 in the tenths place has a value of 0.3.

Amanda [17]

Answer:

4: 32a^5 5: 2a / bc^2

Step-by-step explanation:

4. (2a)^3 / (2a)^-2

  = (2a)^3 * (2a)^2

     = 8a^3 * 4a^2

         = 32a^5

5. 10a^7 b^9 c^6 / 5a^6 b^10 c^8

    = 2a^7 b^9 c^6 / a^6 b^10 c^8

      = 2a / bc^2
