Question

3a²ab-4a²b²b²-6ab•2a+5a³b•0,4ab³

Answer 1

3a²ab-4a²b²b²-6ab•2a+5a³b•0,4ab³=3a³b-4a²$b^{4}$-12a²b+2$a^{4}$$b^{4}$

Answer 2

To simplify the expression 3a²ab - 4a²b²b² - 6ab•2a + 5a³b•0.4ab³, let's go step by step:

1. Combine like terms (terms with the same variables and exponents):

   • 3a²ab and -6ab•2a have the same variables (a and b) and the same exponents (a² and b¹).
   • Combining them, we get: 3a²ab - 6ab•2a = 3a²ab - 12a²b.

2. Now our expression becomes: 3a²ab - 4a²b²b² - 12a²b + 5a³b•0.4ab³.

3. Simplify further:

   • 5a³b•0.4ab³ = 5 * 0.4 * a³ * a * b³ * b = 2a⁴b⁴.

Now, the simplified expression is: 3a²ab - 4a²b²b² - 12a²b + 2a⁴b⁴.
