Oh, dude, B to the power of -1 is just 1 divided by B. It's like flipping B upside down and giving it a little math makeover. So yeah, B to the power of -1 equals 1/B. Math can be pretty chill sometimes, you know?

B4 or B*B*B*B
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.
8 to the power of 8 = 8x8x8x8x8x8x8x8 and does not equal 1 but 1 to the power of 8 does equal 1
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.
