x^(3) = 5.1231010 Take the cube root Hence x = 5.231010^(1/3) x = 1.735915243
what x3 equals 63 is:21x3=63
That's the same as x3 times x3 which equals x6
15
3xyz
y2=x3+3x2
One because if x3 = 1 then x must equal 1
If: x3+1 = 65 Then: x3 = 65-1 And: x3 = 64 So: x = 4 by means of the cube root function on the calculator
IMPOSSIBLE
Realising that 125 is a perfect cube, this is actually pretty easy: x3 + 125 = 0 x3 = -125 x = -5
75x3, /2, +1, x3...10 x3=30 /2=15 +1=16 x3=48 /2=24 +1=25 x3=75
2+4 (which equals 6) x3 (equals 18) +1 = 19
