Need some help with the following and need work shown.

Question

Answer 1

1. 1/96 negative exponent flips the number upside down, 6^-1 becomes 1/6. 4^-2 bocomes 1/4^2 =1/16. (1/6)(1/64) = 1/(6)(16) = 1/96
2. x^18 multiply the exponents
3. 16x^19 add the exponents
4. (x^4)(y^-3) = x^4/y^3
5. a^(7/8) b^0 =1 any number to the zero power =1
6. 500x^6 multiply the exponents: 1/2 times 2 = 1, and 3x2 = 6
7. 35x^11 add the exponents. multiply the coefficients
8. 512x/9 multiply the exponents 1/3 time 3 =1, 0 times -2 =0. anything to 0 power =1
9. ab add the exponents 1+0=1, 3-2 = 1. 1 is implicit a^1b^2 = ab
10. 4 subtract the exponents
11. 2x^2 subtract the exponents, divide the coefficients
12. 6m^(1/2)n^2 subtract the exponents. divide the coefficients
