Answer 1

[•Mυη•]

a) \(100-\left[90+\left(50-2^3.5\right)\right]\)

\(=100-\left[90+\left(50-8.5\right)\right]\)

\(=100-\left[90+\left(50-40\right)\right]\)

\(=100-\left[90+10\right]\)

\(=100-100\)

\(=0\)

b) \(-10-\left(-72+8\right)\)

\(=-10-\left(-64\right)\)

\(=54\)

a) 100 - [90 + (50 - 2³ . 5)]

= 100 - [90 + (50 - 8 . 5)]

= 100 - [90 + (50 - 40)]

= 100 - (90 + 10)

= 100 - 100 = 0

b)  -10 - (-72 + 8)

= -10 - (-64)

= -10 + 64

= 54
