Question

Bantu no. 2 a-f bro ^_^

Answer 1

A.)
Lanjutkan:
√45 = √[9 x 5] = 3√5 [Bener, kok]

b.)
√128 = √[64 x 2] = 8√2

c.)
√[1/63] = √1/√63 = 1/√63
Alias:
= 1/√[9 x 7]
= 1/[3√7]
= 1/3 x 1/7 √7 [Rasionalisasi]
= 1/21 √7

d.)
√0,72 = √[72/100] = √[18/25]
= √18/√25
= √[3 x 2] / 5
= 3√2 x 1/5
= (3/5) √2

e.)
√[2x⁹] = √[x⁸. 2x]
Menjadi:
= x⁴√[2x]

f.) [Apabila salah interpretasi, harap informasikan]
√[x⁶y²z⁴] = √[(x³yz²)²]
Menjadi:
= x³yz²
