Question

(8:2)x4+{[(3²-2³)x2⁴-5]x4¹}

Answer 1

(8 : 2) . 4 + {[(3² - 2³) x 2⁴ -5] x 4¹}

= 4 . 4 + {[(9 - 8) . 16 - 5] . 4}

= 16 + {[1.16 - 5] . 4}

= 16 + { [16 - 5] . 4}

= 16 + { 11.4}

= 16 + 44

= 60

Answer 2

(8:2)x 4+{[(3^2-2^3)x 2^ 4 -5]x 4^1} 4x4 + {[(9-8)x 16-5]x4} 16+ {[(1)x 11] x4} 16 + {[11]x 4} 16 + {44}∴ 16 + 44 = 60
