Question

Escreva as seguintes potencias transformando as bases em 2: a) 4^2
B) 16^3
c)64^1
d) 128^4

Answer 1

(a^x)^y = a^x.y

a) (2^2)^2 = 2^4
b) (2^4)^3 = 2^12
c) (2^6)^1 = 2^6
d) (2^7)^4 = 2^28

Answer 2

a)4²= (2²)² = 2⁴  

b)16³= 16x16x16= 4.096

           4.096= 2¹²

c)64¹= (2⁶)¹= 2⁶

d)128⁴= (2⁷)⁴= 2²⁸
