Question

Aflați $(2x)^{2015}$ știind că:$\frac{3,5*10^2^0^1^5+3,6*11^2^0^1^6+3,7*12^2^0^1^7+3,8*13^2^0^1^8+...+9,9*34^2^9^9^8+10*35^2^9^9^9+11*36^3^0^0^0}{11*36^3^0^0^0+10*35^2^9^9^9+9,9*34^2^9^9^8+...+3,8*13^2^0^1^8+3,7*12^2^0^1^7+3,6*11^2^0^1^6+3,5*10^2^0^1^5}$$: 2=x$

Answer 1

toata fractia aia este egala cu 1 de unde rezulta ca x = 1/2 => $2x^{2015} = 1^{2015} = 1$
