24 - 1 = 2*2*2*2 - 1 = 16 - 1 = 15
4^(-2) = 1/4^2 = 1/16.
1/2
-1 -2 multiplied by another -2 equals 4 .4-5=-1
For anything to the power of a negative, put the number as the denominator in 1/? and then solve (ex: 2 to the power of neg. 2 = 1/2 to the power of 2 = 1/4)
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!
2 minus 2/5 plus 1/2 minus 4 = -1.9
1/4 minus 1/2 is -1/4.
-3 - (-1)= -3 + 1= -2-2
(10+9)+(1−1)+(2−2)+(3−1)+(4−4) = 21This is the same equation rewritten: (10+9)+(3−1) = 21This can be done as 1-1, 2-2, 4-4 cancel themselves out.
It is: 4/5 minus 1/2 = 3/10
Yes and it is: 2 and 1/4 minus 2 = 1/4
36 - 16 = 20
