Answer 1

Ответ:

Объяснение:

При делении степеней с одинаковыми основаниями показатели вычитаются, а основание остаётся без изменений.

Answer 2

Let's solve each of the expressions step by step:

1. (-8)⁵⁰ : (-8)³⁰

We can simplify this expression by subtracting the exponents:

(-8)⁵⁰ : (-8)³⁰ = (-8)^(50-30) = (-8)^20

Since the base (-8) is negative, raising it to an even exponent will result in a positive value:

(-8)^20 = 8^20

Therefore, the answer is 8^20.

2. (3/14)³ : (3/14)²

Similar to the previous expression, we subtract the exponents:

(3/14)³ : (3/14)² = (3/14)^(3-2) = (3/14)^1

The exponent of 1 doesn't affect the value, so the answer is simply:

(3/14)^1 = 3/14

3. (4,1)⁸¹ : (4,1)⁷²

It seems like you might have written the numbers in a different format. If you clarify the format or provide more information, I can help you solve this expression.

4. (a/3)³¹ : (a/3)²¹

Similar to the previous expressions, we subtract the exponents:

(a/3)³¹ : (a/3)²¹ = (a/3)^(31-21) = (a/3)^10

Therefore, the answer is (a/3)^10.

5. (-R)³⁸ : (-R)³⁷

We subtract the exponents:

(-R)³⁸ : (-R)³⁷ = (-R)^(38-37) = (-R)^1

The exponent of 1 doesn't affect the value, so the answer is simply:

(-R)^1 = -R

6. (-6,8)⁴³ : (-6,8)²¹

Once again, it appears that the numbers are written in a different format. If you can clarify the format or provide more information, I can assist you further.
