Question

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

Answer 1

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.
