What do you call a bipyramid with shaved base? In other words, make two identical Egyptian pyramids. Make cuts to create identical vertical walls. The structures' footprints/bases are now identical smaller squares. Glue the squares together so it's a 12-sided solid.
What's the Washington Monument's geometric shape? Is it different if the visible ground touching faces were vertical? Sagittarian Milky Way (talk) 06:32, 23 January 2015 (UTC)
Thanks.

Step 1. Simplify the equation
18*(((-3)^(x/2))^x)-(((-3)^(x/2))^(2*x)) == 81
18 * (-3)^((x^2)/2) - ((-3)^(x^2)) == 81
Step 2. Substitute x^2 with B
18 (-3)^(B/2) - (-3)^B == 81
step 3. Substitute (-3)^B with y
18 Sqrt[y] - y == 81
step 4. solve for all possible value of y (remembering that square root of y has two possible solutions
Step 5. solve for B
step 6. solve for x
QED
oh yeah! I almost forgot, you got to know if you want to work in the REAL domain or in the COMPLEX domain. In other words, do you want only the results in real numbers or in complex numbers. 172.56.32.205 (talk) 17:58, 23 January 2015 (UTC)
