Answer 2

Let's simplify each of these expressions:

2. (-a)³(2a)

First, let's calculate (-a)³:

(-a)³ = (-a) * (-a) * (-a) = -a³

Now, we can multiply -a³ by 2a:

-a³ * 2a = -2a⁴

So, the simplified expression is -2a⁴.

4. (-0.1ab²c)²(100by²)

First, let's simplify the numbers:

(-0.1)² = 0.01 (100)² = 10,000

Now, let's simplify the variables:

(a)² = a² (b²)² = b⁴ (c)² = c² (b)² = b²

Now, we can put it all together:

0.01 * a² * b⁴ * c² * 10,000 * b²

Multiplying the numbers:

0.01 * 10,000 = 100

So, the expression becomes:

100 * a² * b⁴ * c² * b²

Now, we can simplify further:

100a²b⁶c²

So, the simplified expression is 100a²b⁶c².
