Question

Comparati numerele 3⁹⁰ cu 5⁶⁰
Va rog mult,e urgent. Va dau coroana!!!​

Answer 1

Explicație pas cu pas:

$\bf {3}^{90} =3^{3 \cdot30} = \big(3^3 \big)^{30}= \purple{ \underline{27^{30}}}$

$\bf 5^{60} =5^{2 \cdot30} = \big(5^2 \big)^{30}= \blue{ \underline{25^{30}}}$

$\bf 27^{30} > 25^{30} \implies \red{ \underline{3^{90} \: > \:5^{60} }}$

Answer 2

Răspuns:

3⁹⁰ , 5⁶⁰

3⁹⁰=(3³)³⁰=27³⁰

5⁶⁰=(5²)³⁰=25³⁰

avem acelasi exponent comparam baza

27 > 25

3⁹⁰ > 5⁶⁰
