27 X 23 = 210 =1024
If you mean: 2^3 times 2^7 times 2^3 then it equals 8192
343 is 7 to the power of 3 ( 7 x 7 x 7 = 343) To find 7 to the 3 power to the 2/3 power you multiply the exponents and raise 7 to that power: 3 x 2/3 = 2 7^2 = 49
168 23 x 3 x 7 = 8 x 3 x 7 = 168
gcf(35x², 7xy², 21x²y²) = 7x 35x² = 5 times 7 times x² 7xy² = 7 times x times y² 21x²y² = 3 times 7 times x² times y² hcf = 7 times x = 7x (I've written the multiplication as times instead of using the × symbol to avoid confusion with the unknown x.)
3 times 10 to the 8th power divided by 7 times 10 to the negative 7th power equates to: 4.28571428571
If you mean: 2^3 times 2^7 times 2^3 then it equals 8192
second answer: 2²*3*7
168
It is: 2 to the power 4 times 7 to the power 2 = 784

343 is 7 to the power of 3 ( 7 x 7 x 7 = 343) To find 7 to the 3 power to the 2/3 power you multiply the exponents and raise 7 to that power: 3 x 2/3 = 2 7^2 = 49
The prime factorization is 2 to the 2nd power times 3 times 7.
168 23 x 3 x 7 = 8 x 3 x 7 = 168
That's the prime factorization of 2100.
2 to the power of 7 minus 3 to the power of 3 divided by 7 is equal to 124 1/7 ≈ 124.14
7 to the power of 8
2 * 3 * 3 * 5 * 7 = 630
