f)(42:14)la puterea 2*9 la puterea 18:27 la puterea 6=
Va rog imi trebuie repede!!!!!

Answer 1

a)8¹⁵:8¹²=8³
b)13³¹:13³⁰+13=13+13=26
c)7²⁹:7²⁶-7²=7³-7²=7²(7-1)=7²×6=294
d)7¹⁷:7¹³-7³+13⁰=7⁴-7³+1=7³(7-1)+1=7³×6+1=2058+1=2059
e)(11+4)²²:15²⁰-15⁰=15²²:15²⁰-1=15²-1=225-1=224
 f)(42:14)² ×9¹⁸:27⁶=3² ×3³⁶:3¹⁸=3³⁸:3¹⁸=3²⁰
