Answer:
x = 4
Step-by-step explanation:
110ₓ = 40₅ --------- change all to base ten.
the system called binary
1x²+1x ¹+0x⁰ = 45¹+0*5⁰
x² + x + 0 = 20
x² + x – 20 = 0
solve x using Quadratic equation
-1 ± [tex]\sqrt{1^2 - 4* 1 (-20)}[/tex]
x = ------------------------------------
2 * 1
x = -5; x = 4
therefore, x = 4
