Answer 1

А) 3x × (2x)³=3х*8х³=24х⁴
В) -2a × (ab)²= -2а*а²b²= -2a³b²
Д) 2y × (-4y)²=2y*16y²=32y³
Ж) -x × (x²y)⁴= -x*(x²)⁴*y⁴= -x*x^8*y⁴= -x^9y⁴

Answer 2

A) 3x × (2x)^3

To simplify the expression 3x × (2x)^3, we need to apply the rules of exponents.

First, let's simplify the expression inside the parentheses, (2x)^3. This means we need to raise 2x to the power of 3.

When we raise a power to another power, we multiply the exponents. In this case, the exponent of 2x is 3, so we have (2x)^3 = 2^3 * x^3 = 8x^3.

Now, we can substitute this simplified expression back into the original equation: 3x × 8x^3.

To multiply these terms, we multiply the coefficients (3 and 8) and add the exponents of x.

So, the final simplified expression is 24x^4.
