Question

5 minus 3 root 3 upon 5 plus 3 root 3​

Answer 1

Answer:

-26 + 15√3

Step-by-step explanation:

5-3√3 / 5+3√3

We can find the above expression's value by rationalizing it

∴ ( 5-3√3 / 5+3√3 ) × ( 5-3√3 / 5-3√3 )

= ( 5-3√3 )² / (5)² - (3√3)²

= 52 - 30√3 / 25-27

= 52 - 30√3 / (-2)

= -26 + 15√3
