$\huge\mathfrak\purple{♡Solution♡}$

$\sqrt[3]{70 \times 4900} \\ = \sqrt[3]{70 \times 70 \times 70} \\ = 70$

Answer 2

$\sqrt[3]{70\times 4900}$ = 70

Step-by-step explanation:

We have,

$\sqrt[3]{70\times 4900}$

To find, $\sqrt[3]{70\times 4900}$ = ?

∴ $\sqrt[3]{70\times 4900}$

∴ 70 = 7 × 10 and

4900 = 49 × 100 = 7 × 7 × 10 × 10

= $\sqrt[3]{7\times 10\times 7\times 7\times 10\times 10}$

= $\sqrt[3]{7\times 7\times 7\times 10\times 10\times10}$

= 7 × 10

= 70

∴ $\sqrt[3]{70\times 4900}$ = 70

Thus, ​ $\sqrt[3]{70\times 4900}$ = 70
