cât de repede puteri e urgent
DAU COROANA!!

Answer 1

Răspuns:

a) 7 + 6·7 = 7(1+6) = 7·7 = 7²

b) 2·3¹⁴ + 25·3¹⁴ = 3¹⁴(2+25) = 3¹⁴·27 = 3¹⁴·3³ = 3¹⁴⁺³ = 3¹⁷

c) 3·5¹⁵ + 2·5¹⁵ = 5¹⁵(3+2) = 5¹⁵·5 = 5¹⁵⁺¹ = 5¹⁶

d) 3⁶ + 18·3⁴ = 3⁴·3² + 18·3⁴ = 3⁴(9+18) = 3⁴·27 = 3⁴·3³ = 3⁴⁺³ = 3⁷

e) 3¹¹ + 6·3¹⁰ = 3¹⁰·3 + 6·3¹⁰ = 3¹⁰(3+6) = 3¹⁰·9 = 3¹⁰·3² = 3¹⁰⁺² = 3¹²

f) 5²¹ - 4·5²⁰ = 5²⁰·5 - 4·5²⁰ = 5²⁰(5 - 4) = 5²⁰·1 = 5²⁰

Explicație pas cu pas:

Answer 2

a) 7 + 6 • 7 =
7•(1+6)=7•7=7^2

b) 2•3+3^14+25•3^14=
3^14•(2+25)= 3^14•27= 3^14•3^3=3^17

c) 3•5^15+2•5^15=
5^15•(3+2) = 5^15 • 5 = 5^16

d) 3^6+18•3^4=
3^6+3^6=2•3^6

e) 3^11+6•3^10= 3^11+2•3^11=3^11(1+2)=3^11•3=3^12

f) 5^21-4•5^20=
5^20(5-4)=5^20

Succes!
