<h3>Scientific notations</h3>
The standard scientific notation is expressed according to the expression
where
- A is any real value between 1 and 10
- n is any integer
Given the expression
This can be expressed as:
= (5.3 * 4.2)(10⁴ * 10³)
= 22.26 * 10⁷
= 2.23 * 10⁸
Hence the expression written in scientific notation is 2.226* 10⁸

Rewriting the given expression by rationalizing the denominator we proceed as follows:
[√3-√6]/[√3+√6]
to rationalize the denominator we multiply the numerator and the denominator by the conjugate. Thus we shall have:
[√3-√6]/[√3+√6]×[√3-√6]/[√3-√6]
={√3(√3-√6)-√6(√3-√6)}/{√3(√3+√6)-√6(√3+√6)}
=[3-√3√6-√3√6+6]/[3+√3√6-√3√6-6]
simplifying the above we obtain:
[3-2√18+6]/[3-6]
=[3+6-6√2]/(-3)
=[9-6√2]/(-3)
=2√2-3
