Question

escreva as expressoes abaixo na forma de uma so potencia :
a) 7^4.7^2
b)(8^2)^5
C)(0,9)^10:(0,9)4
D){2/3^3)}
e)10^9.10^6
f)6^7.6.6^4
g)(1/2)^5.(1/2)7
h)(o,1)^9.(0,1)^6.(0,1)^5

Answer 1

a) 7^4.7^2 = 7^(4+2) = 7^6
b)(8^2)^5 = 8^(2*5) = 8^10
C)(0,9)^10:(0,9)4 = 0,9^(10-4) = 0,9^6
D){2/3^3)} 
e)10^9.10^6 = 10^15
f)6^7.6.6^4 = 6^(7+1+4) = 6^12
g)(1/2)^5.(1/2)^7 = (1/2)^12
h)(0,1)^9.(0,1)^6.(0,1)^5 = 0,1^20
