Question

\(3^2\left[\left(5^2-3\right);11\right]-2^4+2.10^3\)

80-\(\left[120-\left(13-15\right)^2\right]\)

Answer 1

1)

= 9 . [(25 - 3) : 11] - 16 + 2 . 1000

= 9 . [22 : 11] - 16 + 2 . 1000

= 9 . 2 - 16 + 2 .1000

= 18 - 16 + 2000

= 2 + 2000

= 2002

2)

= 80 - [120 - 4]

= 80 - 116

= -36

Answer 2

\(1).3^2\left[\left(5^2-3\right):11\right]-2^4+2.10^3\)

\(\text{= 9 . [(25 - 3) : 11] - 16 + 2 . 1000}\)

\(\text{= 9 . [22 : 11] - 16 + 2 . 1000}\)

\(=9.2-16+2000\)

\(=18-16+2000\)

\(=2+2000=2002\)

_______________________________

\(2).80-\left[120-\left(13-15\right)^2\right]\)

\(=80-\left[120-\left(-2\right)^2\right]\)

\(=80-\left[120-4\right]\)

\(=80-116\)

\(=-36\)
