the prime factorization of 12 in exponents is 2 to the second power times 3
22 x 3 = 12
you do not do anything when you add numbers with exponents. you just figure out the answer. it is only if you multiply numbers with exponents, where you add the exponents..
Fractional exponents follow the same rules as integral exponents. Integral exponents are numbers raised to an integer power.
Add the exponents
22 x 3 = 12
The GCF is 3. No exponents needed.
the prime factorization of 12 in exponents is 2 to the second power times 3
It is: 12^2 = 144
The same way you divide positive exponents like ( x^-7 ) / ( x^-12) = x^( -7 - - 12) = x^( -7+12) = x^5
12 = 22 x 31
22 x 3 = 12
12 = 2 x 2 x 3
12 2X6 2X2X3 22X31
NEITHER! Look at 4+8 which you know is 12 4 is 2^2 and 8 is 2^3 2^2+2^3=12 but no power of 2 is equal to 12? So the answer is NEITHER. When you multiply numbers, you add the exponents and when you raise and exponent to a power, you multiply exponents. In the example i gave, you could factor out the smallest power and you have 2^2(1+2)=2^2x3=4x3=12 That is how you do this type of problem. Either raise the numbers to their powers and add them, or factor and add.
2^2*3 = 12 2*3^2 = 18
22 x 3 = 12, the GCF
