Answer 1

1). 16a⁴ = (2a)⁴
2). 25m⁴n² = (5m²n)²
3). (3a³b²)² * (-ab³) = -9a⁶b⁴*ab³ = -9a⁷b⁷ = -9(ab)⁷
4). 25a¹⁰ * b¹⁵ * (-0,2a⁻³b⁻²)² = 25*0,04*a¹⁰ *a⁻⁶ *b¹⁵ *b⁻⁴ = a⁴b¹¹

Answer 2

1) To simplify the expression 16a⁴, we can rewrite it as 2⁴ * (a²)². This is because 16 can be expressed as 2⁴ and a⁴ can be expressed as (a²)². Therefore, 16a⁴ simplifies to 16(a²)².

2) To simplify the expression 25m⁴n², we can rewrite it as (5m²)² * (n²). This is because 25 can be expressed as (5m²)² and m⁴ can be expressed as (m²)². Therefore, 25m⁴n² simplifies to (5m²)²n².

3) To simplify the expression (3a³b²)² × (-ab³), we can first square the term inside the parentheses, which gives us (3²a⁶b⁴) × (-ab³). Simplifying further, we get 9a⁶b⁴ × (-ab³). Finally, we can multiply the coefficients and add the exponents of the variables, resulting in -9a⁷b⁷.

4) To simplify the expression 25a¹⁰ × b¹⁵ × (-0.2a⁻³b⁻²)², we can first square the term inside the parentheses, which gives us (-0.2)²(a⁻³)²(b⁻²)². Simplifying further, we get 0.04a⁻⁶b⁻⁴. Finally, we can multiply the coefficients and add the exponents of the variables, resulting in 0.04a⁴b¹¹.

Please note that these simplifications are based on the given expressions and the rules of exponents.
