a ) 125 * 1111^ 3 - 5555^3
b ) 9^5-(3^5)^2 + 8 ^4 - (2^4)^3
c) 2^7 :4^3+3^3 * 27 : 3^5 + (3^1 * 2^4 - 4^2): 2^3

Answer 1

a ) 125 * 1111^ 3 - 5555^3=5^3*1111^3-5555^3=5555^3-5555^3=0

b ) 9^5-(3^5)^2 + 8 ^4 - (2^4)^3=
3^10-3^10 + 2 ^12 - 2=0+0=0

c) 2^7 :4^3+3^3 * 27 : 3^5 + (3^1 * 2^4 - 4^2): 2^3=2^7 :2^6+3^3 * 6-3^3 : 3^5 + (3^1 * 2^4 - 2^4): 2^3=2+3^6 : 3^5 +2^4*(3-1):2^3=2+3 +2^4*2:2^3=2+3 +2^5:2^3=2+3 +2^2=2+3+4=5+4=9

Answer 2

$a ) 125 * 1111^ 3 - 5555^3\\=5^3*1111^3-5555^3\\=5555^3-5555^3\\=0$
[tex]b ) 9^5-(3^5)^2 + 8 ^4 - (2^4)^3\\= 3^{10}-3^{10} + 2 ^{12} - 2\\=0 [/tex]
$c) 2^7 :4^3+3^3 * 27 : 3^5 + (3^1 * 2^4 - 4^2): 2^3\\=2^7 :2^6+3^3 * 6-3^3 : 3^5 + (3^1 * 2^4 - 2^4): 2^3\\=2+3^6 : 3^5 +2^4*(3-1):2^3\\=2+3 +2^4*2:2^3\\=2+3 +2^5:2^3\\=2+3 +2^2\\=2+3+4\\=5+4\\=9$
