Answer 1

1) 6³¹ * 6⁴⁰ : 6⁶⁸ = 6³¹⁺⁴⁰⁻⁶⁸ = 6³ = 216

2) (2¹⁵)⁶ : 2⁸⁵ = 2⁹⁰⁻⁸⁵ = 2⁵ = 32

3) $\frac{243*9}{3^{6} }$ = $\frac{2187}{729}$ = 3

4) 0,9¹¹ * ( $\frac{10}{9}$)¹¹ = (0,9 *  $\frac{10}{9}$)¹¹ = 1¹¹ = 1

5) $\frac{26^{18} }{13^{17} *2^{16} }$ =  $\frac{2^{18}*13^{18} }{13^{17} *2^{16} }$ = 2²*13 = 4*13 = 52

6) $\frac{98^{2} }{28^{3} }$ = $\frac{3,5^{2} *28^{2} }{28^{3} }$ = 3,5² : 28 = 12,25 : 28 = 1225 : 2800 = $\frac{7}{16}$ = 0,4375
