Thank you so much!
In powers, when there are 2 powers, one outside of parentheses and one in, you add to combine powers, not multiply them. So what this problem is saying is (5^2)^3, or 5^5, which equals 3125.
3/(20*288) = 0.0005208333333333, or 1/1920
Because 2 is less than 4.
If a number is subtracted by a larger number, then the difference will be negative.
sqrt(pi) = 1.7724538509055159
Approximately, of course.
This is a paradox. If they all say that the people to their left and right are liars, then they are all telling the truth, but then they would be lying, but then they'd be telling the truth, but then... You get the idea.
Part A: B and D both represent it because 9*3=27 and 3*9=27 and 9+3 and 3+9 both equal 12.
Part B: No because 9-3 does NOT equal 3-9. 6 does not equal -6.
So the base is 10, so (10*12)/2=120/2=60, so the area is 60 un.2
