Answer 1

Resposta:

5) a) $3^5 > 5^3$

b) $250^1 > 1^{250}$

c) $2021^0 > 0^{2021}$

6) a) 500

b) 162

c) 7

Explicação passo a passo:

5)

a) $5^3 = 125$, $3^5 = 243$, logo $3^5 > 5^3$.

b) $1^{250} = 1$, $250^1 = 250$, logo $250^1 > 1^{250}$.

c) $2021^0 = 1$, $0^{2021} = 0$, logo $2021^0 > 0^{2021}$.

6)

a) $5 \times 10^2 = 5 \times 100 = 500$.

b) $2 \times 3^4 = 2 \times 81 = 162$.

c) $7 \times 7^0 = 7 \times 1 = 7$.
