Explications étape par étape
A = 12^5 * 9
A = 2^5*3^5*2^5*3*3
A = 2^(5+5)*3^(5+1+1)
A = 2^10 * 3^7
B = 18^-2 * 48^4
B = 3^-2*3^-2*2^-2*3^4*2^4*2^4*2^4*2^4
B = 2^14 * 3^0 soit(2^14*1 = 2^14)
C = (8^-3 * 24)/(54 * 4^3)
C = ( 2^-3*2^-3*2^-3*3*2*2*2)/(3*3*3*2*2^3*2^3)
C = (2^-9 * 2^3)/(2^7*3^2)
C = 2^(-9+3)/2^7*3^2
C = 2^-6/2^7*3^2
C = 2^(-6-7) * 1/3^2
C = 2^-13 * 3^-2
D = 243/512
D = 3*3*3*3*3/2*2*2*2*2*2*2*2*2
D = 3^5/2^9
D = 3^5 * 1/2^9
D = 2^-9 * 3^5
