7 to the tenth power divided by 7 to the ninth power = 1
n to the power of 9
Four raised to the ninth power is 262,144.
Yes, that is correct.
3 to the ninth power equals 19,683 while 9 to the fourth power equals 6,561 (if i'm not mistaken) so.. 9 to the fourth power (<) 3 to the ninth power
The power and the root cancel each other out and the result is the radicand (the number under the radical sign).
