If 19³ = 6859, find ∛0.006859.(A) 1.9 (B)19 (C) 0.019 (D)0.19

Answer»

Answer:

The CUBE ROOT of 0.0006859 is 0.19

Step-by-step EXPLANATION:

We have 19^3 = 6859

We need to find the cube root of 0.006859

\sqrt[3]{0.006859} = ?

\sqrt[3]{0.006859} = \sqrt[3]{\dfrac{6859}{1000000}} \\= \sqrt[3]{\dfrac {19 \times 19 \times 19}{100 \times 100\times 100}} \\=\sqrt[3]{\dfrac {19^3}{100^3}}\\\\= \dfrac {19}{100}

Now, divide 19 by 100 than we will get 0.19.

\sqrt[3]{0.006859} = 0.19

The cube root of 0.0006859 is 0.19.

So, option (D)= 0.19 is the answer.
