Question

${2}^{3} \: \times {2}^{6} \: \div {2}^{8}$
Va rog repede

Answer 1

Cand avem inmultire intre puteri cu aceeasi baza, adunam exponentii; cand avem impartire intre puteri cu aceeasi baza, scadem exponentii. => 2^(3+6) : 2^8 = 2^9 : 2^8 = 2^(9-8) = 2^1 = 2 "^" inseamna la puterea

Answer 2

${2}^{3} \times {2}^{6} : {2}^{8} = {2}^{3} \times {2}^{6} \times \frac{1}{ {2}^{8} } = 8 \times 64 \times \frac{1}{256} = \frac{512}{256} = 2$
