Question

{2³ + [1 + (3 - 1)² ]} :13

14 + 2. 8²

2.3² - 24: (6.2)

 

Answer 1

a. \(\left\{2^3+\left[1+\left(3-1\right)^2\right]\right\}:13=\left\{8+\left[1+4\right]\right\}:13=\left[8+5\right]:13=13:13=1\)

c. 2.3² - 24 : (6.2)

= 2.9 - 24 : 12

= 18 - 2

= 16

Answer 2

b: \(14+2\cdot8^2=14+2\cdot64=142\)
