Question

Pls send with full solution ;
Cube root of 7

Answer 1

We know that cube root of 1 = 1 and cube root of 8 = 2.

So, the cube root of 7 lies in between 1 and 2.

Lets consider 1.5:

⇒ 1.5 * 1.5 * 1.5

⇒ 3.375

Lets consider 1.7:

⇒ 1.7 * 1.7 * 1.7

⇒ 4.913

Lets consider 1.85:

⇒ 1.85 * 1.85 * 1.85

⇒ 6.33.

Lets consider 1.91:

⇒ 1.9 * 1.9 * 1.9

⇒ 6.96

So, the approximate value is 1.91.

Hope it helps!
