Question

rationalize 16 / √41-5​

Answer 1

Answer:

= 16 / √41 - 5

= We will multiply Numereator and Denominator by √41 + 5

= 16 / √41 - 5 * √41 + 5 / √41 + 5

= Using ( a + b ) ( a - b ) = a² - b² in Denominator

= 16 ( √41 + 5 ) / ( √41 )² - ( 5)²

= 16(√41 + 5) / 41 - 25

= 16(√41 + 5 ) / 16

= √41 + 5
