Question

rationalise these please answer this help guys ​

Answer 1

Step-by-step explanation:

iii) (3 + √2 ) / 4√2

Rationalising,

= (3 + √2 ) 4√2 / 4√2 (4√2)

= 12√2 + 8 / 32

iv) √6 / √2 + √3

Rationalising,

= √6 (√2 - √3) / √2 + √3(√2 - √3)

= √12- √18 / √2^2 - √3^2

= √12- √18 / 2 - 3

= √12- √18 / -1
