Answer:

See below.

Step-by-step explanation:

1/( 1+√2) + 1 /(√2+√3)

Multiply both fractions by the conjugate of the denominators:

= (1 -√2) / (1 +√2)(1 - √2) + (√2 - √3) / (√2 + √3)(√2 - √3)

= (1 - √2) / -1 + (√2 - √3) / -1

= -1 + √2 - √2 + √3

= -1 + √3 as required.

This is further explained below.

<h3>What is an account?</h3>

Generally, An account is a term used in accounting to refer to assets, liabilities, income, costs, and equity.

In bookkeeping, an account is represented by a single page in a ledger, and any changes in value are chronologically documented using debit and credit entries.

These entries, which are also known as posts, are added to a book of final entries or ledger and form a part of it.

In conclusion, the amount of money in your account will be

18 * 8 = 144

Therefore

x=200 - 144

x = $56
