Matematika Tentukan nilai x jika x adalah bilangan bulat

a. x⁵ = 32
b. x² = 64
c. x⁴ = 625
d. x³ = -243​

Tentukan nilai x jika x adalah bilangan bulat

a. x⁵ = 32
b. x² = 64
c. x⁴ = 625
d. x³ = -243​

Jawaban:

x⁵ = 32

x⁵ = 2⁵

x = 2

....

x² = 64

x² = 8²

x = 8

....

x⁴ = 625

x⁴ = 5⁴

x = 5

.....

x³ = -243

x³ = (-7)³

x = -7

a. x⁵ = 32

[tex]x = \sqrt[5]{32} = 2[/tex]

b. x² = 64

[tex] x= \sqrt[2]{64} = 8[/tex]

c. x⁴ = 625

[tex]x = \sqrt[4]{625} = 5[/tex]

d. x³ = -343

x = -7
