Question

I want this immediately please​

Answer 1

(i) 6/13

216= 2×2×2× 3×3×3=2³×3³=6³

2197= 13×13×13 =13³

Then, $\sqrt[3]{ \frac{216}{2197} } = \sqrt[3]{ \frac{ {6}^{3} }{ {13}^{3} } } = \frac{6}{13}$

(ii) 18/11

$4 \frac{508}{1331} = \frac{5832}{1331} = \frac{18 \times 18 \times 18}{11 \times 11 \times 11} = \frac{18}{11}$

(iii) 3.5

$3.5×3.5×3.5= 42.875$
