1. The problem is to calculate $15^{14}$, which means multiplying 15 by itself 14 times. 2. The formula for exponentiation is $a^n = a \times a \times \cdots \times a$ ($n$ times).

1. **State the problem:** Evaluate the expression $-3^2 + 2(-3) + 1$. 2. **Recall order of operations:** Exponents are evaluated before multiplication and addition/subtraction.

1. Let's first state the problem: You have expressions $X = \text{belamder}x$ and $T = \text{be}(\lamder + 1)t$ and you want to check if they are correct. 2. To analyze this, we ne

1. **Problem:** Solve the equation $$|4x - 1| = |x - 3|$$. 2. **Formula and rules:** The absolute value equation $$|A| = |B|$$ implies either $$A = B$$ or $$A = -B$$.

1. **State the problem:** Solve the equation $$9^{x+3} = \frac{3\sqrt{3}}{27^x}$$ for $x$. 2. **Rewrite bases as powers of 3:**

1. **Stating the problem:** We need to find the shape of the region defined by the system of inequalities:

1. Diberikan persamaan: $$5^{x-2y+1} = 25^{x-2y}$$

1. Diketahui fungsi kuadrat $f(x) = ax^2 + bx + c$ yang melalui titik $(0, 3)$ dan mencapai minimum di titik $(-2, 1)$. Kita diminta mencari nilai $a - b + c$. 2. Karena fungsi kua

1. Diberikan persamaan kuadrat $$x^2 - 5x - 1 = 0$$ dengan akar-akar $$x_1$$ dan $$x_2$$. Kita diminta mencari nilai $$x_1^2 - 4x_1 + x_2$$. 2. Dari sifat akar-akar persamaan kuadr

1. **State the problem:** Given two functions $f(x) = x^2$ and $g(x) = 2x + 1$, find the following combined functions: - $(f + g)(x)$

1. Problem: Find $(f+g)(1)$ where $f(x) = \frac{3x+1}{x+1}$ and $g(x) = \frac{x^{-5}}{x}$.\n\n2. Formula: $(f+g)(x) = f(x) + g(x)$. We evaluate each function at $x=1$ and then add.

1. **State the problem:** Evaluate $\ln\left(e^{\sqrt{3}}\right)$.\n\n2. **Recall the logarithm rule:** For any positive number $a$ and exponent $b$, $\ln\left(e^b\right) = b$ beca

1. **State the problem:** We need to solve the equation $$\frac{2x+4}{x-1} = 3$$ for $x$. 2. **Formula and rules:** To solve rational equations, multiply both sides by the denomina

1. **Problem:** Solve the equation $$\left(\frac{16}{18}\right)^{x-1} = \left(\frac{6}{9}\right)^{\frac{x}{2}}$$. 2. **Step 1: Simplify the bases.**

1. **State the problem:** Simplify the fraction $\frac{231}{1001}$ to its lowest terms and find the least common denominator (LCD) for the given options. 2. **Prime factorization:*

1. **State the problem:** Reduce the fraction $\frac{231}{1001}$ to its lowest terms. 2. **Formula and rules:** To reduce a fraction, divide numerator and denominator by their grea

1. **State the problem:** Simplify the expression $$\frac{18a - 5ab}{6a^2}$$. 2. **Identify the terms:** The numerator is $18a - 5ab$ and the denominator is $6a^2$.
