Finding Prime Number Pairs with Same Digits Up to 100

The numbers 13 and 31 are indeed both prime numbers and share the same digits, which makes them a fascinating pair. To find other such pairs of prime numbers up to 100, we need to identify all prime numbers in this range first. Prime numbers are defined as numbers greater than 1 that have no […]

How to Multiply 2 Digit Numbers by 2 Digit Numbers

Multiplying two-digit numbers can seem a bit tricky at first, but with the right method, it becomes quite manageable. Let’s break it down step by step. Consider the two-digit numbers 23 and 45. To multiply these, follow these steps: Break down the numbers: Split each number into its tens and units. For 23, it’s 20 […]

Find the values of x for which the series converges x 3n2n

To determine the values of x for which the series converges, we first express the series explicitly. The given series can be interpreted as: S = ∑ (x * 3^n * 2^n) This can be rewritten as: S = x * ∑ (3 * 2)^n Now, simplify the series term: S = x * ∑ […]

How do you find the vertex of a quadratic function?

To find the vertex of a quadratic function, you can use the formula derived from the function’s standard form, which is written as f(x) = ax² + bx + c. The x-coordinate of the vertex can be calculated using the formula x = -b / (2a). Once you have the x-coordinate, you can substitute this […]

Which function represents a reflection of f(x) = 508x across the x-axis?

To reflect a function across the x-axis, you need to negate the value of the function. In this case, if we start with the function f(x) = 508x, the reflection across the x-axis can be represented by the function: g(x) = -f(x) = -508x This transformation results in the same input values for x but […]
