Mastery emerges not through force alone, but through deliberate engagement with the principles at play Worth keeping that in mind..
Step 1: Express 3125 as a Power of 5
The first crucial step is to express the number 3125 as a power of 5. Recall that powers of 5 are numbers where 5 is multiplied by itself a certain number of times. We can systematically find this by repeatedly dividing 3125 by 5:
- 3125 / 5 = 625
- 625 / 5 = 125
- 125 / 5 = 25
- 25 / 5 = 5
- 5 / 5 = 1
We divided by 5 a total of 5 times, so 3125 can be written as 5⁵.
Step 2: Substitute into the Equation
Now, substitute 5⁵ for 3125 in the original equation:
5⁵ × 5¹⁰ = 3x
Step 3: Apply the Product of Powers Rule
The product of powers rule states that when multiplying powers with the same base, you add the exponents. In this case, both terms involve the base 5. Therefore:
5⁵ × 5¹⁰ = 5^(5+10) = 5¹⁵
Our equation now becomes:
5¹⁵ = 3x
Step 4: Solve for x
To isolate x, divide both sides of the equation by 3:
x = 5¹⁵ / 3
Step 5: Calculate 5¹⁵
Calculating 5¹⁵ can be done in stages. We know 5⁵ = 3125. Therefore:
5¹⁵ = 5⁵ × 5¹⁰ = 3125 × 5¹⁰
We already know 3125 × 5¹⁰ = 3x from the original problem. So, 5¹⁵ = 3x.
Now, substitute this back into our equation for x:
x = (3x) / 3
x = x
This might seem like a trick! But let's re-examine our steps. In practice, we found that 3125 * 5¹⁰ = 5¹⁵. So, 5¹⁵ = 3x. This means x = (3125 * 5¹⁰) / 3.
Let's calculate this:
x = (3125 * 9765625) / 3 x = 3046875000 / 3 x = 1015625000
Conclusion
By systematically applying the properties of exponents and algebraic manipulation, we successfully solved the equation 3125 × 5¹⁰ = 3x. Plus, the final answer is x = 1,015,625,000. The key steps involved expressing 3125 as a power of 5, applying the product of powers rule, and isolating x. The ability to confidently manipulate exponential equations is a valuable skill applicable across various scientific and mathematical disciplines, empowering individuals to approach challenges with a structured and analytical mindset. This example demonstrates that seemingly complex mathematical problems can be effectively tackled by breaking them down into smaller, manageable steps and understanding the underlying principles. Continued practice and a solid grasp of foundational concepts are essential for achieving proficiency in this area.
