Question

calculati: 2^30:2^15. (2^20+2^20):2^15. (2^18+2^18):(2^17+2^17) va roooggg multtt acummm?!!!!!???!!

Answer 1

2^30:2^15= daca baza este aceeasi la impartire exponentii se scad adica 2^(30-15)=2^15
(2^20+2^20):2^15 se poate de scris ca 2^20:2^15+2^20:2^15=2^5+2^5 = 32*2=64
(2^18+2^18):(2^17+2^17) =2*2^18:2*2^17=doi cu doi se simplifica si ramane 2^18:2^17=2^1=2

Answer 2

2³⁰:2¹⁵=2¹⁵
(2²⁰+2²⁰) : 2¹⁵= 2²⁰*(1+1): 2¹⁵= 2²⁰*2 : 2¹⁵= 2¹⁶
(2¹⁸+2¹⁸): (2¹⁷+2¹⁷)= 2¹⁸*(1+1) : 2¹⁷*(1+1)= 2¹⁹: 2¹⁸= 2¹=2
