Find the cube root of 8*7*9*49*3.

Find the cube root of 8*7*9*49*3

$$\sqrt[3]{8*7*9*49*3} = \sqrt[3]{2^33^37^3} = 2*3*7 = 42$$

$${\mathtt{8}}{\mathtt{\,\times\,}}{\mathtt{7}}{\mathtt{\,\times\,}}{\mathtt{9}}{\mathtt{\,\times\,}}{\mathtt{49}}{\mathtt{\,\times\,}}{\mathtt{3}} = {\mathtt{74\,088}}$$

$${\sqrt{{\sqrt{{\mathtt{74\,088}}}}}} = {\mathtt{16.498\: \!215\: \!337\: \!821\: \!55}}$$
