Well, isn't that a happy little question! When you see 4 to the power of minus 2, it means you're taking the number 4 and raising it to the power of -2. In other words, it's like dividing 1 by 4 squared, which equals 1/16. Just remember, there are no mistakes, just happy little accidents in math!
4^(-2) = 1/4^2 = 1/16.
4-3 = 1/64
-2 times -2 = plus 4 since minus times minus is plus
Your question can mean one of two things: a) -(2)2 = -4 b) (-2)2 = 4
It is plus 4
4^(-2) = 1/4^2 = 1/16.
36 - 16 = 20
4-3 = 1/64
4 -22= -2 x -2 double minus there =4
-2 times -2 = plus 4 since minus times minus is plus
No.
1/2
(-2)^4 = -2 x -2 x-2 x-2 = +16 ( a minus times a minus is plus)
0.0000115 = 1.15 X 10 -5 ---------------------is this what you mean? Not - 4 but - 5 .
-4 basically you take 5 from one!
243 - 32 = 211
If you mean 2/9 minus 2/15 then it is 4/45 in its lowest terms
