Answer 1

Answer:

We have to find what 6–√6 multiplied by 27−−√27 is equal to.

It can be written in the mathematical form as:

⇒6–√×27−−√→(1)⇒6×27→(1)

We know that 6=3×26=3×2 therefore, on substituting, we get:

⇒6–√=3×2−−−−√⇒6=3×2

Now we know the property of radicals that a−−√×b√=ab−−√a×b=ab, therefore, we can write:

⇒6–√=3–√×2–√→(2)⇒6=3×2→(2)

Now we know that 2727 can be written as 3×3×33×3×3 therefore, on substituting, we get:

⇒27−−√
