Question

a) 3²+ [2⁴ - 5. (4-7)=
b) (-2 + 6)³ + [3⁴: (-5-2²)]=

Answer 1

a) 9+[16-5.(-3)] = 9+[16-15] = 9+1 = 10

b) 64+[81/(-5-4)] = 64+[81/-9] = 64+(-9) = 55

Answer 2

a) 3^2 + [2^4 -5(4-7)]∴ 9 + [16-20+35]∴ 9+ [51-20]∴ 9+ 31=40∴



b) (-2+6)^3 + [3^4:(-5-2^2)]∴4^3 + [81:(-9)]∴ 64 + [-9] ∴

64 -9 = 55
