Question

Calcule:

a)-
$400 \frac{1}{2} =$

b)-
$8 \frac{1}{3} =$

c)-
$169 \frac{1}{2} =$

d)-
$(3 \frac{1}{3} ) ^{3} =$
​

Answer 1

Explicação passo-a-passo:

a)-

400^1/2 =

fatorando 400

400 = 4 * 100 = 2² * 10² = 20²

(20² )^1/2= 20¹ = 20 >>>>> resposta

multiplica expoentes >> 2 * 1/2 = 2/2 = 1

b)-

( 8 )^1/3

fatorando

8 = 2³

(2³ )^1/3 = (2 )¹ = 2 >>>>>> resposta

multiplica expoentes >>>3 * 1/3 = 3/3 = 1 >>>

c)-

169^1/2

169 = 13²

( 13² )^1/2 = ( 13 )¹ = 13 >>>>>resposta

multiplica expoentes >>>2* 1/2 = 2/2 =1 >>>>

d)-

(3 inteiros 1/3 )³ =

3 inteiro 1/3 = ( 3 * 3 ) + 1 = 9 + 1 = 10/3 >>>>

reescrevendo

( 10/3)³ = 10/3 * 10/3 * 10/3 = 1000/27 >>>>resposta

Answer 2

Olá Thauane, (◕દ◕)

a)- 1/2 de 400

400:2= 200

200.1= 200.

b)- 1/3 de 8

8/1.1/3=

8/3= 2,6.

c)- 1/2 de 169

=>É igual a raiz

quadrada de 169.

√169= 13.

d)- 3⅓=

2.3+1/3=

7/3.

Espero ter lhe ajudado,

Bons Estudos!!! ❤️✨❤️
