Question

(√3+√75)*(√3-√75)+√75/√3( дробь)

Answer 1

(√3+√75)*(√3-√75)+√75/√3=3-75+√75/3=-72+√25=-72+5=-67
√75/3 - тут берешь под общий корень

Answer 2

Let's simplify the given expression step by step:

1. First, let's simplify (√3 + √75) * (√3 - √75):

Using the difference of squares formula (a^2 - b^2 = (a + b)(a - b)), we get:

(√3 + √75) * (√3 - √75) = (√3)^2 - (√75)^2 = 3 - 75 = -72

2. Next, we have to calculate √75 / √3:

To simplify this, we can rationalize the denominator by multiplying both the numerator and denominator by √3:

√75 / √3 = (√75 * √3) / (√3 * √3) = √(75 * 3) / 3 = √225 / 3 = 15 / 3 = 5

Now, let's put both results together:

(-72) + (5) = -67

So, the simplified expression is -67.
