I want to put the variable as a legend but in form of power of some amount this is the variable
x=-1.1;
then in the result i want to see 10^-1.1
figure
plot(Ratio,Final_1,'k-x','linewidth',2)
grid on
legendInfo = ['SNR target for BER 10^' num2str(x)];
legend(legendInfo,'Location','southeast')
xlabel('Ratio')
ylabel('SNR')
problem i have is this part "'SNR target for BER 10^' num2str(x)" because it is not showing like 10^x

Use the sprintf function:
legendInfo = sprintf('SNR target for BER 10^%f', x);

My pleasure.
I thought you wanted integers rounded to the next lowest integer. The '%.1f' is the correct option for one decimal-place floating-point precision.
