Answer 1

Resposta:

4

Explicação passo-a-passo:

X=

$x=(5^2)^3.(5^3:5^2)^4\\x=(5^2^.^3).(5^3^-^2)^4\\x=(5^6).(5^1)^4\\x=(5^6).(5^1^.^4)\\x=5^6.5^4\\x=5^6^+^4\\x=5^1^0$

Y=

$y=(5^9)^2:(5^4.5^2)^2\\y=(5^9^.^2):(5^4^+^2)^2\\y=(5^1^8):(5^6)^2\\y=(5^1^8):(5^6^.^2)\\y=5^1^8:5^1^2\\y=5^1^8^-^1^2\\y=5^6$

X:Y=

$x:y=5^1^0:5^6\\x:y=5^1^0^-^6\\x:y=5^4$
