Question

Comparați:
$a) \frac{3 {}^{20} }{2 {}^{30} } \: si \: 1$
​

Answer 1

Răspuns:

Explicație pas cu pas:

3^20 = (3^2)^10 = 9^10

2^30 = (2^3)^10 = 8^10

9^10 > 8^10

9^10/8^10 > 1

3^20/2^30 > 1

​

Answer 2

$\it \dfrac{3^{20}}{2^{30}}=\dfrac{(3^2)^{10}}{(2^3)^{10}}=\dfrac{9^{10}}{8^{10}}>1$
