b)4¹³÷8⁶+7³-5²×[625÷5⁴+16÷(7×3²-55)]
c)18×[1+3⁷×3⁵³+7⁸⁴÷7¹⁴+(5⁴)²⁰]÷(13⁰+3⁶⁰+7⁷⁰+5⁸⁰) URGENT! DAU COROANA!!​

Answer 1

Răspuns:

A 3²+15¹⁰÷15⁹-2011⁰×1= (2011⁰=1)

9+15-1

23

B4¹³×2¹³÷8⁶+343-25×[625÷625+16÷(7×9-55)]

8¹³÷8⁶+343-25×(1+16÷8)

8⁷+343-25×3

2.097.152+343- 75

2.097.495-75=2.097.420

C 18×[1+3⁶⁰+7⁷⁰+5⁸⁰]÷(1+3⁶⁰+7⁷⁰+5⁸⁰)

18 - pentru ca cele două ecuati dau 1 iar ×18=18
