Question

1)b⁵:b²; 2)y¹¹:y⁷; 3)a⁷:a⁷; 4)b⁹:b⁹.​

Answer 1

Ответ:

Объяснение:

1) b⁵:b²=b⁵-²=b³

2) y¹¹:y⁷=y¹¹-⁷=y⁴

3)a⁷:a⁷=a⁷-⁷=a⁰=1

4) b⁹:b⁹=b⁹-⁹=b⁰=1

Answer 2

Ответ:

$b {}^{5} \div b {}^{2} = b {}^{5 - 2} = b {}^{3} \\ y {}^{11} \div y { {}^{} }^{7} = y {}^{11 - 7} = y {}^{4} \\ a {}^{7} \div a {}^{7} = 1 \\ b {}^{9} \div b {}^{9} = 1$

Answer 3

It seems like you've provided a list of expressions with variables and exponents. These expressions involve exponentiation, and in each case, you're comparing a base raised to a certain power with the same base raised to another power. Let's break down each expression:

1. b⁵ : b² In this expression, you are comparing b raised to the power of 5 with b raised to the power of 2. The result is b^(5-2) = b³.

2. y¹¹ : y⁷ Here, you are comparing y raised to the power of 11 with y raised to the power of 7. The result is y^(11-7) = y^4.

3. a⁷ : a⁷ In this case, you are comparing a raised to the power of 7 with itself raised to the power of 7. The result is the same, so it's equal to 1.

4. b⁹ : b⁹ Similar to the third expression, you are comparing b raised to the power of 9 with itself raised to the power of 9. The result is also equal to 1.

So, to summarize:

1. b⁵ : b² = b³
2. y¹¹ : y⁷ = y⁴
3. a⁷ : a⁷ = 1
4. b⁹ : b⁹ = 1
