Question

cu explicație daca se poate​

Answer 1

Răspuns:

Explicație pas cu pas:

a)

2^3*4^3 = 2^3*(2^2)^3 = 2^3*2^6 = 2^9

b)

2^7*16 = 2^7*2^4 = 2^11

c)

2^15*4^12*8^6 = 2^15*(2^2)^12*(2^3)^6 = 2^15*2^24*2^18 = 2^57

d)

9^2*27^3*3^7 = (3^2)^2*(3^3)^3*3^7 = 3^4*3^9*3^7 = 3^20

e)

4^22 : 2^40 = (2^2)^22 : 2^40 = 2^44 : 2^40 = 2^4

f)

3^6*4^6 : 12^4 = (3*4)^6 : 12^4 = 12^6 : 12^4 = 12^2

g)

(5^10*25^2)^3 : 5^40 = (5^10*5^4)^3 : 5^40 = (5^14)^3 : 5^40 = 5^42 : 5^40

= 5^2

h)

125^6 : 25^4 *(5^3)^11 = (5^3)^6 : (5^2)^4 *5^33 = 5^18 : 5^8 *5^33

= 5^10*5^33 = 5^43
