Tentukan hasil dari :√2 x √52√2 x 3√52√12 + 5√3

Tentukan hasil dari :

1. √2 × √5

2. 2√2 × 3√5

3. 2√12 + 5√3

Jawab :

1. : sqrt{2} times sqrt{5} \ = sqrt{2 times 5} \ = sqrt{10}

2. : 2 sqrt{2} times 3 sqrt{5} \ = 6 sqrt{2 times 5} \ = 6 sqrt{10}

3. : 2 sqrt{12} + 5 sqrt{3} \ = 4 sqrt{3} + 5 sqrt{3} \ = 9 sqrt{3}

PENYELESAIAN

sqrt{2} times sqrt{5} \ = sqrt{2 times 5} \ = sqrt{10} \ \ 2 sqrt{2} : times 3 sqrt{5} \ = 2 times 3 sqrt{2 times 5} \ = 6 sqrt{10} \ \ 2 sqrt{12} + 5 sqrt{3} \ = 2 times 2 sqrt{3} + 5 sqrt{3} \ = 4 sqrt{3} + 5 sqrt{3} \ = 9 sqrt{3}
