nyatakan operasi berikut dalam bentuk akar paling sederhana: a).√50+√98 b).3√27-√48

a)
√50 + √98
= √(25 x 2) + √(49 x 2)
= 5√2 + 7√2
= 12√2

b).
3√27 - √48
= 3(√(9 x 3)) - √(16 x 3)
= 3(3√3) - 4√3
= 9√3 - 4√3
= 5√3

a]
V50 + V98
= V(25×2) + V(49×2)
= V25V2 + V49V2
= 5V2 + 7V2
= 12V2

b]
3V27 - V48
= 3V(9×3) - V(16×3)
= 3V9V3 - V16V3
= 3(3)V3 - 4V3
= 9V3 - 4V3
= 5V3
