Question

Ma ajuta si pe mn cnv. va rog?!!

Answer 1

3^7:3^2=3^7-2=3^5 adica (3×3×3×3×3)=243
5^9:5^4:5^3=5^9-4-3=5^2=(5×5)=25
2^10:2^8=2^2=(2×2)=4
6^15:6^14=6^1=6
16^4:16^4=16^0=1(orice nr. la puterea 0=1)
7^25:7^20:7^3=7^2=(7×7)=49
la impartire exponentii se scad.

Answer 2

A) 7-2=5.....deci e 7^5 (^=la puterea)
B)9-4-3=2...deci e 5^2=25
C)10-8=2.....deci e 2^2=4
D)15-14=1.....deci e 6^1=6
E)4-4=0.......deci e 16^0=1
F) 25-20-3=2.....deci e 7^2=49

Sper ca te-am ajutat!
