Question

Simplify :

(4root 5 -3root 2) (3 root 5- 5root 2 )​

Answer 1

Answer:

$(4 \sqrt{5} - 3 \sqrt{2} )(3 \sqrt{5} - 5 \sqrt{2} ) \\ \\ = 12 \sqrt{25} - 20 \sqrt{10} - 9 \sqrt{10} + 15 \sqrt{4} \\ \\ = 12 \times 5 - 29 \sqrt{10} + 15 \times 2 \\ \\ = 60 - 29\sqrt{10} + 30 \\ \\ = 90 - 29 \sqrt{10}$

hope this much helps uh ❣️
