bantu jawab pliss bsk dikumpulin

Kalo mau jawaban yg lbih sederhana bisa dirasionalkan akar2 nya

yg atas dulu
7.(4)^-3/2 . (27)^5/6
= 7.2^(-3/2×2) . 3^(5/6×3)
= 7.2^-3 . 3^5/2
= 7/8 × 9√3
= 63√3/8
yg bawah
{4^5/4 - 6(27)^-1/3} 4^-2
{2^(2×5/4) - 6(3)^(3×-3)} 2^-4
{2^5/2 - 6(3)-¹} 2^-4
{2^5/2 - 6(1/3)} 2^-4
{2^5/2 - 2} 2^-4
2^(5/2-4) - 2^(1-4)
2^(5/2-8/2) - 2^-3
2^-3/2 - (1/8)
1/2√2 - 1/8
√2/4 - 1/8
2√2/8 - 1/8
(2√2 -1)/8
baru di gabung
63√3/8 ÷ (2√2 - 1)/8
63√3/8 × 8/(2√2 - 1)
63√3 / (2√2 - 1)
63√3 / (2√2 - 1) × (2√2 + 1)/(2√2 + 1)
126√6 + 63√3 / 8-1
63(2√6 + √3) / 7
