Question

7^-15/7^-13= ^ - степень / - дробь

Answer 1

Ответ:

Пошаговое объяснение:

(7^-7*7^-8) /(7^-13)=7^(-7-8) / 7^-13=7^-15 / 7^-13=7^[-15-(-13)]=7^(-15+13)=7^-2=1/7^2=1/49

Ответ: 1/49

Answer 2

To simplify the expression (7^(-15))/(7^(-13)), you can apply the rule of division with the same base, which states that when you divide two numbers with the same base, you subtract their exponents.

In this case, the base is 7, so you subtract the exponents:

7^(-15) / 7^(-13) = 7^(-15 - (-13))

To simplify further, you can subtract the exponents:

7^(-15 - (-13)) = 7^(-15 + 13)

Now, you add the exponents:

7^(-15 + 13) = 7^(-2)

Therefore, the simplified expression is 7^(-2).
