oticare exercitiu dau coroana

Answer 1

10. a) 10⁶⁰:10⁵⁸=10²=100
b) (3¹⁴x7)²:3²⁶=3²⁸:3²⁶x7=3²x7=63
c) (3⁶)⁸:(3²)²⁴=3⁴⁸:3⁴⁸=1
d) (2⁵)⁴:2¹⁸=2²⁰:2¹⁸=4
e) (11²⁰¹¹x2²⁰¹⁰):22²ˣ⁵ˣ²⁰¹=11²⁰¹¹x2²⁰¹⁰:22²⁰¹⁰=11²⁰¹¹x2²⁰¹⁰:11²⁰¹⁰x2²⁰¹⁰=11x1=11
f) 2²³:2²¹:2+3³²:3³¹x3=2²:2+3x3=2+9=11

11. a=11x{3+5x[200-3x(442-80x5)]}+17 = 11x[3+5x(200-126)]+17 = 11x(3+5x74)+17 = 4120
b=100+2x[2+2x(222-2x20)] = 100+2x(2+2x182) = 100+2x366 = 100+732 = 732.
Mai mare este a.
Sper sa fie corecte.
