Answer 1

Ответ: 9

Пошаговое объяснение: 12-3=9

Answer 2

It looks like there might be a mistake in your expression. It seems you have written "а¹" which could be interpreted as "a to the power of 1," but then you also have "а" later in the expression. If you meant "a" to the power of 1, it is just "a" itself.

If we assume you meant $4a^1 - a$ and you're substituting $a = x = 3.??$, then you can replace $a$ with $x$ in the expression:

$4x - x$

Combine like terms:

$3x$

So, if $a = x = 3.??$, then $4a^1 - a$ would be equal to $3x$, where $x$ is approximately 3.?? (the exact value depends on the specific digits in place of "?").
