Simplify each expression.

$$\left(\left({\mathtt{8}}{\mathtt{\,\times\,}}{{\mathtt{b}}}^{\left({\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right)}{\mathtt{\,\times\,}}{\mathtt{9}}{\mathtt{\,\times\,}}{{\mathtt{t}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{5}}}}\right)}\right){\mathtt{\,\times\,}}\left({\mathtt{8}}{\mathtt{\,\times\,}}{{\mathtt{b}}}^{\left({\frac{{\mathtt{5}}}{{\mathtt{3}}}}\right)}{\mathtt{\,\times\,}}{\mathtt{9}}{\mathtt{\,\times\,}}{{\mathtt{t}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{5}}}}\right)}\right)\right)$$

$${\mathtt{8}}{\mathtt{\,\times\,}}{{\mathtt{b}}}^{\left({\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right)}{\mathtt{\,\times\,}}{\mathtt{9}}{\mathtt{\,\times\,}}{{\mathtt{t}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{5}}}}\right)}{\mathtt{\,\times\,}}{\mathtt{8}}{\mathtt{\,\times\,}}{{\mathtt{b}}}^{\left({\frac{{\mathtt{5}}}{{\mathtt{3}}}}\right)}{\mathtt{\,\times\,}}{\mathtt{9}}{\mathtt{\,\times\,}}{{\mathtt{t}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{5}}}}\right)}$$

$${\mathtt{5\,184}}{\mathtt{\,\times\,}}{{\mathtt{b}}}^{\left({\frac{{\mathtt{7}}}{{\mathtt{3}}}}\right)}{\mathtt{\,\times\,}}{{\mathtt{t}}}^{\left({\frac{{\mathtt{4}}}{{\mathtt{5}}}}\right)}$$  or  $${\mathtt{5\,184}}{\mathtt{\,\times\,}}{\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{{\mathtt{b}}}^{{\mathtt{7}}}}}{\mathtt{\,\times\,}}{\sqrt[{{\mathtt{{\mathtt{5}}}}}]{{{\mathtt{t}}}^{{\mathtt{4}}}}}$$

(8b^(2/3)*9t^(1/5)) (8b^(5/3)*9t^(3/5)) ......  rearrange.......

[8b^(2/3) * 8b^(5/3)] * [ 9t^(1/5) * 9t^(3/5) ] =

[64 b^(7/3)] * [ 81 t^(4/5) ] =

5184* b^(7/3)* t^(4/5)

And that's it.....!!!!
