Question

1) y11:y7 2) b9:b9 Выполните деление

Answer 1

Ответ:

Объяснение:

1) y¹¹/y⁷=y¹¹⁻⁷=y⁴ при у≠0

($a^m/a^n=a^{m-n}$, если а≠0, m>n)

2) b⁹/b⁹=b⁹⁻⁹=b⁰=1 при b≠0

(любое число, кроме 0, в нулевой степени равно единице, если а≠0, то а⁰=1)

Answer 2

Ответ:

Объяснение:

1) y^11/y^7=y^(11-7)=y^4

2)b^9/b^9=b&0=1

Answer 3

1. y11:y7

To divide y11 by y7, you can simplify the expression by subtracting the exponents in the denominator from the exponents in the numerator. Remember that when you divide two numbers with the same base (in this case, "y"), you subtract the exponents:

y11 ÷ y7 = y^(11-7) = y^4

So, the result of y11:y7 is y^4.

2. b9:b9

When you divide b9 by b9, you have the same base (b) with the same exponent (9) in the numerator and denominator. In this case, any non-zero number divided by itself equals 1:

b9 ÷ b9 = 1
