Question

(корень3-корень5)(корень3+корень5)

Answer 1

по формуле сокращёнава умнаженыия получица 3-5=-2

Answer 2

To simplify the expression (корень3-корень5)(корень3+корень5), we can use the difference of squares formula, which states that (a - b)(a + b) = a^2 - b^2.

In this case, a = корень3 and b = корень5.

So, (корень3 - корень5)(корень3 + корень5) = (корень3)^2 - (корень5)^2.

Now, let's calculate:

(корень3)^2 = 3 (since the square root of 3 squared is 3), (корень5)^2 = 5 (since the square root of 5 squared is 5).

Therefore,

(корень3 - корень5)(корень3 + корень5) = 3 - 5 = -2.

The simplified expression is -2.
