Question

√ a+√ b/√ a-√ b

Answer 1

Multiply numerator and denominator y the conjugate of sqrta-sqrtb which is sqrta + sqrtb

Answer 2

\[\sqrt{a +\sqrt{b \div \sqrt{a -\sqrt{b}}}}\]

Answer 3

im still a bit confusedd

Answer 4

a times a and b times b?

Answer 5

\[\frac{\sqrt{a}+\sqrt{b}}{\sqrt{a}-\sqrt{b}}\]

Answer 6

Is that the problem?

Answer 7

it should be like that right ?

Answer 8

yes yes thats the problem

Answer 9

kk like he said multiplie by the conjugate

Answer 10

yes like @mertsj wrote

Answer 11

of denominator

Answer 12

\[\frac{\sqrt{a}+\sqrt{b}}{\sqrt{a}-\sqrt{b}}\times\frac{\sqrt{a}+\sqrt{b}}{\sqrt{a}+\sqrt{b}}=\frac{a+2\sqrt{ab}+b}{a-b}\]

Answer 13

thats different i thought we were supposed to multiply them by each other

Answer 14

no always you should mutiply by the conjugate of denominator

Answer 15

denominator si √ a+√ b then you multiply by √ a-√ b

Answer 16

and like mertsj solved it it cant be simplified furrther cuz they r vaiables right?

Answer 17

good job :)

Answer 18

thank u guys so much :D i really appreciate it

Answer 19

^^

Answer 20

:)

Answer 21

yw

Answer 22

:)

Answer 23

theres one more its \[\sqrt{5+1}\div \sqrt{5-1}\]
this would be done like that too
