There are three ways:
Either 27 raised to the power of 2
or 9 raised to the power of 3
or 3 raised to the power of 6
the 2 ways are intrusive rock and extrusive rock
9 + 9 + 9 = 27 3 x 3 x 3 = 27
it is a diatomic which makes it O2 and it has -2 charge
Magnesium that has lost 2 electrons.
2+2-2!=10
2 to the 6th, and 4 to the 3rd
3^4 or 9^2
One way is 4 the power of 2
8000 is:20380001 (that's all that i could find)
81 = 9^2 = 3^4 ("^" means "to the power of" - ^2 = squared, ^3 = cubed, etc.)
25 to the 2nd power, 5 to the 4th
27^2 = 729
729 is not prime. 729 = 3 * 3 * 3 * 3 * 3 * 364 is not prime. 64 = 2 * 2 * 2 * 2 * 2 * 2
2 ways
3^3 = 27 27^2 = 729 (3^3)^2 = 3^6 = 729
2/3 x 729 = 486
20/100 or 2/10
