x to the power a divided by x to the power b is x to the power (a - b) When a and b are equal then this is x to the power a divided by x to the power a, ie 1. x to the power (a - a) = x to the power zero. Things which are equal to the same thing are equal to each other, so 1 = x to the power zero.
10-1 = 1/10 A number raised to a negative power is equal to the reciprocal of the number raised to the power. So a-b = (1/a)b = 1/ab
B4 or B*B*B*B
8 to the power of 8 = 8x8x8x8x8x8x8x8 and does not equal 1 but 1 to the power of 8 does equal 1
1 megabyte is equal to 1048576 bytes. This is equal to 220, or 2 to the power 20. Therefore, 9 megabytes are equal to 1048576 x 9 = 9,437,184 bytes.
x to the power a divided by x to the power b = x to the power (a - b), ie xa/xb = xa-b. When a = b, xa/xb = 1 and a - b = 0 so xa-b = x0. Rearranging gives x0 = 1. This is true for ALL non-zero values of x.
No.Neither are commutative: a - b does not equal b - a, and a/b does not equal b/a.Neither is associative: (a - b) - c does not equal a - (b - c), and (a/b)/c does not equal a/(b/c).Examples of these are:4 - 2 does not equal 2 - 4.1/3 does not equal 3/1.(6 - 5) - 1 does not equal 6 - (5 - 1).(10/2)/2 does not equal 10/(2/2).
1 raised to any power is always equal to 1.
b = 7 (74 = 2,401)
(B^-1)B = 1 B^(-1xB) = 1/(B^B)
Anything to the power zero is equal to 1 by definition.
By definition (-1)*(-1)=1.(-a)*(-b)(-1)*(a)*(-1)*(b)(-1)*(-1)*(a)*(b)(a)*(b) ■
