Question

(2√10-√3) (3√5-√5) sove it​

Answer 1

$(2 \sqrt{10} - \sqrt{3} )(3 \sqrt{5} - \sqrt{5} )$

$(2 \sqrt{10} - \sqrt{3} )(2 \sqrt{5)}$

$2 \sqrt{5} (2 \sqrt{10} - \sqrt{3} )$

$2 \sqrt{5} \times 2 \sqrt{10} + 2 \sqrt{5} \times - \sqrt{3}$

$4 \sqrt{50} - 2 \sqrt{15}$

$4 \sqrt{25 \times 2} - 2 \sqrt{15}$

$5 \times 4 \sqrt{2} - 2 \sqrt{15}$

$20 \sqrt{2} - 2 \sqrt{15}$

u'r done!!

Thnx✌️♥️~

Answer 2

Answer:

20√2-2√15

Step-by-step explanation:

= 2√10(3√5)-2√10(√5)-√3(3√5)+√3×√5

= 6×5√2-2×5√2-3√15+√15

= 30√2-10√2-3√15+√15

= 20√2-2√15
