Question

Calculează : 1024:16+{[26 la puterea a 2:(2*5 la puterea a 2-74:2)+28]:(80:5)+45}*3-14

Answer 1

1024:16+{[26²:(2*5²-74:2)+28]:(80:5)+45}*3-14 =
=64+{[26²:(2*25-37)+28]:16+45}*3-14 =
=50+{[26²:(50-37)+28]:16+45}*3 =
=50+[(2²×13²:13+28):16+45]*3 =
=50+[(2²×13+28):16+45]*3 =
=50+[(52+28):16+45]*3 =
=50+(80:16+45)*3 =
=50+50*3 =
=50+150=
=200
=64+50*3-14 =
