Given $$\sqrt 2 $$ = 1.414, the value of $$\sqrt 8 $$ $$\, + $$ $${\text{2}}\sqrt {32} $$ $$\, - $$ $$3\sqrt {128} $$ $$\,\, + $$ $${\text{4}}\sqrt {50} $$  is = ?

2.
Simplify : $$\frac{{16 \times 32}}{{9 \times 27 \times 81}} = ?$$

3.
Simplify : $$\frac{{343 \times 49}}{{216 \times 16 \times 81}} = ?$$

4.
Simplify : (3)8 × (3)4 = ?

5.
The value of $${\left( {3 + 2\sqrt 2 } \right)^{ - 3}}$$   $$ + {\left( {3 - 2\sqrt 2 } \right)^{ - 3}} = ?$$

6.
The value of $${\text{2}} + \sqrt {0.09} \, - \,\root 3 \of {0.008} \, - \,75\% $$       of 2.80 is = ?

7.
$$\sqrt {2 + \sqrt {2 + \sqrt {2 + ......} } } $$      is equal to ?

8.
The value of $${\left( {256} \right)^{\frac{5}{4}}}$$  is = ?

9.
$${\left( 6 \right)^4} \div {\left( {36} \right)^3} \times 216 = {6^{\left( {? - 5} \right)}}$$

10.
