Correct Answer
B
Explanation
if 125 =20sub10, find x 125subx =20sub10whereby using base 3 125sub3 = 1x3sup2 +2x3sup1 +5x3= 1x9+2x3+5x1= 9+6+5=20sub10 therefore 125sub3 = 20sub10therefore x =3To find the value of x in the equation 125x = 20, we need to isolate x on one side of the equation. To do this, we divide both sides of the equation by 125:125x / 125 = 20 / 125Simplifying, we get:x = 20 / 125Evaluating the division, we find:x = 0.16Therefore, x is equal to 0.16.To find the value of x in the equation 125x = 20�₀, we can start by dividing both sides of the equation by 125:125x / 125 = 20�₀ / 125This simplifies to:x = 0.16�₀So, the value of x is 0.16 in base 10.
