To solve x^7 = 9
take the 7th root: x = 9^(1/7)
Alternatively,
take logs 7*log(x) = log(9)
log(x) = log(9)/7
x = 10^{log(9)/7}
or use natural logs, so that x = e^{ln(9)/7}
If x=9, x=9
x ≠11 9 + x = 21 9 + x - 9 = 21 - 9 x = 12
The value of x that satisfies -9 multiplied by x equals 1 is x = -1/9.
9 x 9 x 9 = 729
9 X 9 = 81
x=9
-9
If X = 9 then 5X would = 5 x 9, which is 45.
9
There is no answer it it just stays 9-x
X = 72 72 divided by 9 equals 8
If x-3x=18 then x equals -9
