5. a 5x5 pangkat 3
Nomor 4 :
= 3/akar 3 X akar 3/akar 3
= 3 akar 3/3
= 1 akar 3
#semoga sesuai yaa...
2. (i) a × a × a × a = a⁴
(ii) a² + a² = 2a²
(iii) 2² × a² = 4a²
(iv) a + a + a + a = 4a
Jawaban: C
5. 5³ + 5³ + 5³ + 5³ + 5³
= 5 × 5³
Jawaban: A
G2:
2. L sisi = 64
s² = 64
s = √64
s = 8 cm
diagonal ruang = s√3
diagonal ruang = 8√3
Jumlah semua diagonal ruang
= 2 × 8√3
= 16√3 cm
4. 4/(√8 - √5)
= 4/(√8 - √5) × (√8 + √5)/(√8 + √5)
= 4(√8 + √5)/((√8)² - (√5)²)
= 4(√8 + √5)/(8 - 5)
= 4(2√2 + √5)/3
= (8√2 + 4√5)/3
