Answer:

The value of x is 3

Step-by-step explanation:

Given:

[tex]x^3 = 27[/tex]

To Find:

x = ?

Solution:

We Know that

[tex]a = (a^3)^\frac{1}{3}[/tex]

[tex]a = (a)^\frac{3}{3}[/tex]

We can write 27 as [tex]3 \times 3 \times 3[/tex] = [tex]3^3[/tex]

Taking cube root on both sides

[tex](x^3)^{\frac{1}{3} }= (3^3)^{\frac{1}{3}}[/tex]

[tex]x^{\frac{3}{3}} = 3^{\frac{3}{3}}[/tex]

[tex]x^1 = 3^1[/tex]

x = 3
