27 is 3 to the 3rd power, and 64 is 2 to the 6th power, so the only number that goes into both evenly is one (1).
A number to a negative power is just moved to the denominator: (27^-1)/2 = 1/ (27^1)*2=1/(27*2)=1/54
2 x 2 x 2 x 2 x 2 x 2 x 2 x 2= 256

3 to the third power (3^3) is equal to 27. 4 to the third power (4^3) is equal to 64. Combining the 2 answers (27*64) we have 1968.
2 x 2 x 2 x 2 x 2 x 2 x 2 x 2= 256
25*28/27 = 25+8-7 = 26 = 64

Evaluate -6 to the power of 2
64 8 to the power of 2 is the same as 8x8 The answer is 64.
Evaluate simply means work out. You times the first number by itself. The second number which is is small and beside the top corner of the first number decides how many times the first number gets times by itself. Here are 4 examples: 2 to the power of 4 = 2 x 2 x 2 x 2= 16 3 to the power of 3 = 3 x 3 x 3= 27 4 to the power of 3= 4 x 4 x 4= 64 5 to the power of 5 = 5 x 5 x 5 x 5 x 5= 3125
To simplify the fraction 64/27, we need to find the greatest common divisor (GCD) of the numerator and denominator, which is 1 in this case. Therefore, the fraction 64/27 is already in its simplest form because there are no common factors other than 1 that can be divided out from both numbers.
