Para calcular o valor das potencias, elevamos cada número pela potencia:
(4/5) ² = 4²/5² = 16/25
(1/4) ³ = 1³/4³ = 1/(4.4.4) = 1/64
(1/3) ⁵ = 1⁵/3⁵ = 1/243
(9/10) ² = 9²/10² = 81/100
(1/2)⁴ = 1⁴/2⁴ = 1/16
(9/15)¹ = 9¹/15¹ = 9/15
-------------------------------------------------------------------------------------------------------------------------
calcule o valor de:
(3/2)² = 3²/2² = (3.3)/(2.2) = 9/4
(2/3)⁴ = 2⁴/3⁴ = 16/81
2/3⁴ = 2/81
2/3 4 = Não entendi essa
-------------------------------------------------------------------------------------------------------------------------
calcule:
√9/4 = √9/√4 = 3/2
√49/81= √49/√81 = 7/9
√1/49 = √1/√49 = 1/7
√36/64 = √36/√64 = 6/8
√100/81 = √100/√81 = 10/9
√1/100 = √1/√100 = 1/10
-------------------------------------------------------------------------------------------------------------------------
calcule.
3/4 - 1/2 = →mmc(4,2)=4⇒(3-1.2)/4 = 1/4
3/8 + 3/2 = →mmc(8,2)=8⇒(3+3.4)/8 = 15/8
3/5 + 3/4 + 3/10 = →mmc(5,4,10)=20⇒(3.4+3.5+3)/20 = 30/20
6/5 - 1/4 - 3/10= →mmc(5,4,10)=20⇒(6.4-1.5-3)/20 = 16/20
-------------------------------------------------------------------------------------------------------------------------
calcule.
4 + 1/2 + 2/3= →mmc(1,2,13)=6⇒(4.6+1.3+2.3)/6 = 33/6
1/3 + 2 +1/5= →mmc(3,1,5)=15⇒(1.5+2.15+1.3)/15 = 38/15
0/10 + 3/20 + 11/30= 3/20 + 11/30→mmc(20,30) =60
⇒(30.5+3.20)/60 = 210/60 = 21/6
2 - 1/3 - 1/5= →mmc(1,3,5)=15⇒(2.15-1.5-1.3)/15 = 22/15
-------------------------------------------------------------------------------------------------------------------------
calcule e simplifique, se necessario
23/7 + 1/3 - 2 + 1/6 →mmc(7,3,1,6)=42
⇒(23.6+1.14-2.42+1.7)/42 = 75/42
4 2/3 - 1 1/2 + 7/8 ?

malaquita:
a décima pergunta no meu livro esta assim: 2/3 e o numero 4 esta ao lado do 3 embaixo junto dele ao invés de ser encima como normalmente é entendeu? Se entendeu me responda por favor, e obrigado.
