Question

Calculati folosind regulile de calcul cu puteri:

(5 la puterea 7x 5 la puterea8):5 la puterea 3

7 la puterea 5x7 la puterea 7)7 la puterea 2

(3 la puterea 6x3 la puterea 9):3 la puterea 4

(2 la puterea 7)totul la 3:(2x2 la puterea 10)

(7 la puterea 4)totul la 8:(7x7 la puterea 21)

Answer 1

5⁷⁺⁸⁻³=5¹²
7⁵⁺⁷⁻²=7¹⁰
3⁶⁺⁹⁻⁴=3¹¹
2⁷ˣ³:2¹¹=2²¹⁻¹¹=2¹⁰
7⁴ˣ⁸:7²²=7³²⁻²²=7¹⁰

Answer 2

(5^7•5^8):5^3=
=5^15:5^3=
=5^12

(7^5•7^7):7^2=
=7^12:7^2=
=7^10

(3^6•3^9):3^4=
=3^15:3^4=
=3^11

(2^7)^3:(2•2^10)=
=2^21:2^11=
=2^10

(7^4)^8:(7•7^21)=
=7^32:7^22=
=7^10

^ = la puterea
