a) \(4^3 . 12 - 2^4 . 15 \)
= 64 . 12 - 16 . 15
= 768 - 240
= 528
528 = \(2^4 . 3 . 11 \)
b) \(7^2 . 12 - 120 : 2^3\)
= 49 . 12 - 120 : 8
= 588 - 15
= 573
573 = 191 . 3
c) \(2500 : 5^2 + 2^4 . 30\)
= 2500 : 25 + 16 . 30
= 100 + 480
= 580
580 = \(2^2 . 5 . 29\)
d) \(123 - (2^3 . 3^2 - 2^4 . 3)\)
= 123 - (8 . 9 - 16 . 3)
= 123 - (72 - 48)
= 123 - 24
= 99
99 = \(3^2 . 11\)
