simplify the expression 28b to the 6/7 be well this is the same thing this is the same thing as 28 over 7 times B to the sixth over B and I did it this way so that we have B we have B to the sixth over B to some other power and this is over B which is the same thing as B to the first and we could simplify this using exponent properties and 28 over 7 we can just clearly simplify because 28 is divisible by 7 28 divided by 7 is just 4 so that is just 4 and then B to the 6 divided by B to the 1 that's just going to be B to the 6 minus one power so times B to the 6 minus 1 or B to the fifth so our answer is 4 B to the fifth
