Question

2 si 3 va rog !! Dau coroana

Answer 1

2. a= ((3²+2*3³):21)^63 = 
= ((1+2*3)*3²:21)^63 = 
= ((1+6)*9:21)^63 = 
= (7*9:21)^63 =  
= 3^63

b= ((4³-3*4²):4)^42 = 
= ((4-3)*4²:2²)^42 = 
= (1*(2²)²:2²)^42 = 
= (2^4:2²)^42 = 
= (2²)^42 = 
= 2^84

comparati a si b
a=3^63 si b=2^84
a > b.

3. Nu stiu!
