Jawab:= 30√2 - 40
Penjelasan:Sifat distributifa(b±c) = (a×b) ± (a×c)
Oleh karena itu2√5(3√10 - 4√5)= (2√5 × 3√10) - (2√5 × (4√5))= (2√5 × 3√(2×5)) - (2×4×√5²)= (2√5 × 3√2 × √5) - (2×4×5)= (2√5√5 × 3√2) - (8×5)= (2×√5² × 3√2) - (8×5)= (2×5 × 3√2) - 40= (10 × 3√2) - 40= 30√2 - 40

Jawab:
= 30√2 - 40
Penjelasan:
Sifat distributif
a(b±c) = (a×b) ± (a×c)
Oleh karena itu
2√5(3√10 - 4√5)
= (2√5 × 3√10) - (2√5 × (4√5))
= (2√5 × 3√(2×5)) - (2×4×√5²)
= (2√5 × 3√2 × √5) - (2×4×5)
= (2√5√5 × 3√2) - (8×5)
= (2×√5² × 3√2) - (8×5)
= (2×5 × 3√2) - 40
= (10 × 3√2) - 40
= 30√2 - 40
