Math Problem Statement

(-4)³ : (-4)⁵ / (-4)⁴

Solution

Let's solve the expression (4)3(4)5÷(4)4\frac{(-4)^3}{(-4)^5} \div (-4)^4.

First, let's break down the problem step by step.

  1. Calculate the numerator: (4)3=(4)×(4)×(4)=64(-4)^3 = (-4) \times (-4) \times (-4) = -64

  2. Calculate the denominator: (4)5=(4)×(4)×(4)×(4)×(4)=1024(-4)^5 = (-4) \times (-4) \times (-4) \times (-4) \times (-4) = -1024

  3. Simplify the fraction: (4)3(4)5=641024=116\frac{(-4)^3}{(-4)^5} = \frac{-64}{-1024} = \frac{1}{16}

  4. Now, divide by (4)4(-4)^4: (4)4=(4)×(4)×(4)×(4)=256(-4)^4 = (-4) \times (-4) \times (-4) \times (-4) = 256 116÷256=116×1256=14096\frac{1}{16} \div 256 = \frac{1}{16} \times \frac{1}{256} = \frac{1}{4096}

So, the final result is:

(4)3(4)5÷(4)4=14096\frac{(-4)^3}{(-4)^5} \div (-4)^4 = \frac{1}{4096}

Here are 5 related questions to expand your understanding:

  1. What is the value of (3)2(3)4÷(3)\frac{(-3)^2}{(-3)^4} \div (-3)?
  2. How do you simplify expressions with negative exponents?
  3. What happens when you multiply two negative numbers?
  4. How does the power of a negative number affect its sign?
  5. Can you generalize the rule for aman\frac{a^m}{a^n} when m>nm > n?

Tip: When dividing exponents with the same base, you can subtract the exponents directly: aman=amn\frac{a^m}{a^n} = a^{m-n}.
