[tex]\underbrace{4^5+4^5+4^5+4^5}_{\text{ada 4 faktor}}=4^5\times4=4^{5+1}=4^6=(2^2)^6=2^{2\times6}=2^{12}\\\\\\\underbrace{3^5+3^5+3^5}_{\text{ada 3 faktor}}=3^5\times3=3^{5+1}=3^6\\\\\\\underbrace{6^5+6^5+6^5+6^5+6^5+6^5}_{\text{ada 6 faktor}}=6^5\times6=6^6=(2\times3)^6=2^6\times3^6\\\\\\\underbrace{2^5+2^5}_{\text{ada 2 faktor}}=2^5\times2=2^6[/tex]
Selesaikan :
[tex]$\begin{align} \frac{2^{12}}{\not3^6}\times\frac{\not2^6\times\not3^6}{\not2^6}&=\boxed{2^{12}} \end[/tex]
Sehingga, nilai n adalah 12.
4. 4²+4²+4²+4²/ 3^5+3^5+3^5 × 6^5+6^5+6^5+6^5+6^5+6^5/ 2^5+2^5 = 2^n, maka nilai n adalah

64(4² + 4² + 4² + 4²) / (3^5 + 3^5 + 3^5) x (6^5 + 6^5 + 6^5 + 6^5 + 6^5 + 6^5)/(2^5 + 2^5) = 4²(1 + 1 + 1 + 1) / 3^5(1 + 1 + 1) x 6^5(1 + 1 + 1 + 1 + 1 + 1) / 2^5(1 + 1)
= 4²(4) / 3^5(3) x 6^5(6) / 2^5(2)
= 4³ / 3^6 x 6^6 / 2^6
= (2²)³ / 3^6 x 6^6 / 2^6
= 2^6 / 3^6 x 6^6 / 2^6
= (2^6 x 6^6) / (3^6 x 2^6)
= 12^6 / 6^6
= 2^6
2^6 = 2^n
n = 6
maka nilai n adalah 6
