Plot 6 directly above 6. Plot root83 between 9 and 10 but nearer to 9 since its value in 3 significant figures is 9.11,
Plot root40 between 6 and 7 but nearer to 6 since its value in 3 significant figures is 6.32,
Plot root64 directly above 8 since 8x8=64,
And lastly plot 7.5 just in between 7 and 8,
Hope this helps ;)
