Question

add (7 root 7 + 4 root 3 ) and ( 4 root 3 - 3 root 3 )​

Answer 1

Answer:

you will first have to rationalize the denominator.

As the denominator in this question is (7+4 root 3), we can rationalize it by multiplying it by (7- 4 root 3). We will also have to multiply the numerator by this same number.

(4+3√3)(7-4√3)/ (7+4√3)(7-4√3)

28-16√ +21√3-36/ 49-48 (opening the bracket)

-8+5√3/1

5√3-8(ans.)
