1) Thực hiện phép tính

a) 20 : 2² + 5⁹ : 5⁸

= (20:4) + (5⁹ : 5⁸)

= 5+5

= 10

b) 2 x { 198-[ 158-946+4)x2]}

= 2 x { 198-[(-788)+4x2]}

= 2 x { 198-[(-784)x2}

= 2 x { 198-(-1568)}

= 2 x 1766

= 3532

c) 2011-(21+ 314: 312 ) :15

= 2011- (21+9):15

= 2011- 30:15

= 2011-2

= 2005

Vì 2n-1 là số nguyên dương nhỏ nhất

\(\Rightarrow\) 2n-1 = 1

\(\Rightarrow\) 2n = 1+1

\(\Rightarrow\) 2n = 2

\(\Rightarrow\) n = 2:2

\(\Rightarrow\) n = 1

Vậy số nguyên n là 1.
