Question

if √35 is 5.9160 then value of √7+√5/√7-√5​

Answer 1

Answer:

The square root of 35 is a number whose square gives the original number. By trial and error method, we can see that, there does not exist any integer whose square is 35.

The value of √35 is 5.91607978309961...

To check this answer, find (5.91607978309961)2 and we can see that we get 34.999... which is very close to 35.

Is the Square Root of 35 Rational or Irrational?

A rational number is a number which can either be:

either terminating

or non-terminating and has a repeating pattern in its decimal part.

In the previous section, we saw that: √35 = 5.91607978309961...

Clearly, this is non-terminating and the decimal part has no repeating pattern. So it is NOT a rational number. Thus, √35 is an irrational number.

Answer 2

Answer:

7+3√5 3+√5 7-3√5 3-√5 - (7+3√5) (3-√5) — (7 — 3√5) (3 – (3+√5) (3-√5) 6+2√5-6+2√5 3² - (√5)2 By using (a + b)(a - b) = a² - b²
