b) 2×9+5×16-3×16 = 18+80-48=98-48=50

2) a) 3¹⁹×3²⁵:3¹² = 3¹⁹+²⁵-¹²=3³²

b) (2⁴)⁵:2⁷×4³=2⁴×⁵-⁷×2⁶=2²⁰-⁷+⁶=2¹⁹

c) (5²×2)¹²:5²⁴+2⁸:4²-4⁵×2²=

=5²⁴×2¹²:5²⁴+2⁸:2⁴-2¹⁰×2²=

=5⁰×2¹²+2⁴-2⁸=

=1×2¹²+2⁴-2⁸=

=4096+16-256=

=3856

3. a) 3¹⁹×2⁶+3¹⁸×10+3²⁰×2²=

=3¹⁸(3×2⁶+10+3²×2²)

=3¹⁸(3×64+10+9×4)

=3¹⁸(192+10+36l

=3¹⁸×238
