Verified answer

In the answer conjugate of (5 + √2) i. (5 – √2) will be there.

so numerator will be 8(5 – √2)

so option A. C, D ruled out

so answer is B

8/(5 + √2)

= 8(5 – √2)/(5 + √2)(5 – √2)

= 8(5 – √2)/(25 – 2)

= 8(5 – √2)/(23)

option B

----

8/(5 + √2)

Answer:

B. 8(5 - √2)/23

Hi,

8/(5+√2) multiple choice?

. 8

-------- =

5+√2

. 8(5-√2)

------------------ =

(5+√2)(5-√2)

8(5-√2)

------------ =

25 - 2

8(5-√2)

------------ <==ANSWER

. 23

A. (5-√2)/23

B. 8(5-√2)/23 <==ANSWER

C. 8/23

D. 8(5+√2)/(5-√2)

I hope that helps!! :-)

B. Multiply the numerator and denominator by the conjugate of the denominator, 5 – √(2)
