Vă rog frumos sa mă ajutati la ex E, E.Mulțumesc

Answer 1

Efectuați:
a) (3²×7)³=(3²)³×7³=3^6×7³
b) (2^5×5³)²=(2^5)²×(5³)²=2^10×5^6
c) (2³×3×5²×7)³=(2³)³×3³×(5²)³×7³=2^9×3³×5^6×7³
d) (2×5)^8–(10⁴)²=10^8–10^8
e) (3²×5)^5–3^10×5^5=3^10×5^5–3^10–5^5
f) (3⁴×2)²–3^8×3=3^8×2²–3^8×3

Efectuați:
a) 7^58–7^56=7^2×29–7^2×28=(7²)^29–(7²)^28
b) 3^75 : 3^69–(3²)³=3^6–3^6
c) 4³ : 2⁴=4³ : (2²)²=4³ : 4²=4¹=4
d) (2^10)^10 : (2^10×2^10)=2^100 : 2^100=2^0
e) (3⁴×5²×7^5)^8 : (3^32×5^10×7^40)=3^32×5^16×7^40 : 3^32×5^10×7^40
= 3^0×5^6×7^0
