Question

scrie ca putere, după model: 2^7×4=2^7×2^2=2^9 a)3^12×27= b)5^15:25= c) 2^20:4^8= c)1000^6:100^4​

Answer 1

Răspuns:

a). = 3 la12 x 3 la 3=3 la 15

b). =5 la15: 5 la2=5 la13

c). = 2 la20: 4 la8=2 la20: 2 la16=2 la4=16

d). =10la2

Explicație pas cu pas:

Answer 2

a) 3^12 x 27 = 3^12 x 3^3 = 3^15

b) 5^15 : 25 = 5^15 : 5^2 = 5^13

c) 2^20 : 4^8 = 2^20 : (2^2)^8 = 2^20 : 2^16 = 2^4

d) 1000^6 : 100^4 = (10^3)^6 : (10^2)^4 = 10^18 : 10^8 = 10^10
