It is: (-4)^2 +(-4) -9 = 3 when x is equal to -4
4 x 4 is equal to 16.
4 x 4 x 4 x 4 x 4 x 4 (or 4^6) is equal to 4,096.
If x + 4 is less than or equal to 22, that means that x is less than or equal to 18
2 x 4 x 8 x 10 is equal to 640.
4 x 7 x 5 is equal to 140.
If you mean: x+4 = 38 then x = 34
x >= 4 So x can be 4,5,6,7 etc., BUT not -4.
log3(x)=4 x=3^4 x=81
-14
9 x 4 x 10 = 360
512, or 4 x 4 x 4 x 4 x 2
