Answer 1

Daca avem inmultire cu aceeasi baza dar exponentii diferiti atunci se vor aduna exponentii intre ei

Daca avem impartire baza la fel si exponentii diferiti atunci se vor scadea exponentii intre ei

a) 2/3^(5+4)= 2/3^9

b) 5/7^(8-6)= 5/7^2

c) 5/7^(2×3)=5/7^6

d) (4/5×7/8)^6= 7/10^6

e) [(4×3)/15]^(3×20)= 12/15^60

Answer 2

Răspuns:

a)2/3^(5+4)=2/3^(9);

b)5/7^(8-6)=5/7^(2);

c)5/7^(2×3)=5/7^(6);

d)(4/5+7/8)^(6)=32/40+35/40=67^(6);

e)2^(2)=4, 4×3/3×5^(3×20)=12/15(3=4/5^(60)
