A power is a shortcut for repeated multiplication. The exponent tells you how often the factor must appear. For example, 84 = 8 x 8 x 8 x 8. Similarly, a multiplication is a repeated addition.
8/32 factor out the 8 8*1/8*4 you can eliminate the 8 as it is a factor in both numerator and denominator 1/4 ---------simplest form
8/81 is already in simplest form. The only common factor between 8 & 81 is 1.
8 to the power of 1 is 8. That is because 8 is the base and 1 is the exponent or the power in this mathematical operation. Exponents indicate a shorthand for repeated multiplication of the same thing by itself. So 8 to the power of 1 is just 8, while 8 to the power of 2 would be 8x8, and so on.
104/48 factor out a 8 8*13/8*6 as 8 appears in both numerator and denominator it can be eliminated 13/6 -------- simplest form
