Question

a)[600-(40:2³+3.5³)]:5                    b)16.12²-(4.23²-59.4)

c)2¹⁰⁰-(1+2+2²+2³+...+2⁹⁹)                    d)169.2011⁰-17.(83-1702:23+1²⁰¹²)+2⁷:2⁴

Đề bài:Thực hiện phép tính

Answer 1

a: \(\left[600-\left(40:2^3+3\cdot5^3\right)\right]:5\)

\(=\left[600-5-375\right]:5\)

\(=44\)

b: \(16\cdot12^2-\left(4\cdot23^2-59\cdot4\right)\)

\(=16\cdot144-4\cdot\left(23^2-59\right)\)

\(=2304-4\cdot470\)

\(=424\)

 

Answer 2

c: Ta có: \(2^{100}-\left(1+2+2^2+2^3+...+2^{99}\right)\)

\(=2^{100}-2^{100}+1\)

=1

d: Ta có: \(169\cdot2011^0-17\cdot\left(83-1702:23+1^{2012}\right)+2^7:2^4\)

\(=169-17\cdot\left(83-74+1\right)+2^3\)

\(=177-17\cdot10\)

=7
