Question

A- 1/a =√7 a×a×a×a +1/a×a×a×a =

Answer 1

Ответ:

49$\frac{1}{49}$

Пошаговое объяснение:

ну, вопрос не задан, но ответ очевидный:

из 1/a = $\sqrt{7}$  виражаем а:
а = 1 / $\sqrt{7}$

а*а*а*а+1/а*а*а*а = а^4 + 1/a^4 = 49 + 1/49 = 49$\frac{1}{49}$
a^4 = 7^2 = 49

Answer 2

To simplify the given expression, let's start by multiplying both sides of the equation by 'a' to get rid of the fractions:

a * (1/a) = a * √7 * a * a * a * a + 1/a * a * a * a

On the left side, the 'a' and (1/a) cancel each other out, leaving us with:

1 = a * √7 * a * a * a * a + 1/a * a * a * a

Next, we can simplify the terms on the right side:

1 = a * √7 * a^4 + 1 * a^3

Since we have 'a' raised to different powers, let's combine them:

1 = √7 * a^(1+4) + a^3

Simplifying further:

1 = √7 * a^5 + a^3

At this point, we have simplified the equation as much as possible.
