√18-3√75+√75 Adalah A. -8√2-4√3 B. 3√2-12√3 C. 12√2+3√3 D. 10√2+2√3 E. 2√2+10√3

(akar 18) - (3 akar 75) + (akar 75)
= (akar (9 × 2)) - (3 akar (25 × 3)) + (akar (25 × 3))
= (3 akar 2) - (3 × 5 akar 3) + (5 akar 3)
= (3 akar 2) - (15 akar 3) + (5 akar 3)
= (3 akar 2) - (10 akar 3)

= √18 - 3√75 + √75
= √18 - 2√75
= √(9×2) - 2√(25×3)
= 3√2 - 2.5√3
= 3√2 - 10√3

Opsi gak ada

Semoga berguna +_+
