Question

1)√8/√18 2)√45+3√5Решите пожалуйста)

Answer 1

1) √8/√18=2√2/3√2=2/3
2) √45+3√5=3√5+3√5=6√5

Answer 2

Solution:

To solve the given expressions, let's break them down step by step:

1) √8/√18:

To simplify this expression, we can simplify the square roots individually and then divide the results.

√8 can be simplified as 2√2, and √18 can be simplified as 3√2.

So, the expression becomes (2√2)/(3√2).

Since the square root of 2 appears in both the numerator and denominator, we can cancel them out, leaving us with:

2/3.

Answer: 2/3.

2) √45 + 3√5:

To simplify this expression, we can simplify the square roots individually and then add the results.

√45 can be simplified as √(9 * 5), which further simplifies to 3√5.

So, the expression becomes 3√5 + 3√5.

Combining like terms, we get:

6√5.

Answer: 6√5.
