Question

help vs ak

Answer 1

a: \(=26\cdot\left(75+51-26\right)=26\cdot100=2600\)

b: \(=\left(-35+21\right)+\left(-11+11\right)+135=135-35+21=121\)

c: \(=-50-\left\{\left(20+8\right):\left(-2\right)+34\right\}\)

\(=-50-\left\{-14+34\right\}\)

=-50-20

=-70

d: \(=16\cdot5-\left[131-\left(-9\right)^2\right]=80-50=30\)
