Answer 1

A) 3^ -2  * 3^4 = 3^-2 + 4 = 3^2 
     3² = 3 * 3 = 9
b) 5^2 * 5^-6 = 5^2+(-6)= 5^-4= (1/5)^4
    1/5^4 = 1/5 * 1/5 * 1/5 *1/5 = 1/625
c) 4^-4 * 4^2 = 4^-4 + 2 = 4^-2 = (1/4)^2
    (1/4)² = 1/4 * 1/4 = 1/16
d) 2^-8 * 2^5 = 2^-8+5= 2^ -3 = 1/2^3
    (1/2)³ = 1/2 * 1/2 * 1/2 = 1/8
e) (2/3)^-8 *(2/3)^6 = (2/3)^-8 + 6 = (2/3)^-2 = (3/2)^2
    (3/2)² = 3/2 * 3/2 = 9/4
f) (4/7)^-4 * (4/7)^ 5 = (4/7)^-4 + 5 = (4/7)^1
     (4/7)^1 = 4/7
g) (1 2/3)^10 * (1 2/3)^-8 = (5/3)^10 * (5/3)^-8= (5/3)^10 -8= (5/3)^2
     (5/3)² = 5/3 * 5/3 = 25/9
h) (2,6)^-4 * (2,6)^3 = (2,6)^-4 + 3 = (2,6)^-1 = (26/10)^-1 = (10/26)^1
    (10/26)^1 = 10/26
