Answer:

The two numbers are 36 and 9

Step-by-step explanation:

Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48

We know that: n <44, 48

Let's try some values:

45 - 40 = 4

45- 36 = 9

45- 28 = 17

45- 24 = 21

Pattern: The lesser a natural numer's absolute value, the greater [larger number] it produces. (Bold = "larger numbers")

We recognize something: 36 + 9 = 45 and 36 is exactly 4 times greater than 9.

PLEASE HELPPP ASAPP!!<br><br> Combine and simplify the following radical expression.
Greeley [361]

After demonstrating the procedure by algebraic means, the expression (2\sqrt[3]{12} )\cdot (3\sqrt[3]{2} ) <em>is equivalent to</em> 6\cdot \sqrt[3]{24}.

In this question we proceed to <em>simplify</em> (2\sqrt[3]{12} )\cdot (3\sqrt[3]{2} ) by <em>algebraic</em> means into a <em>single</em> <em>radical</em> expression when possible, whose procedure is shown below and explained by appropriate definitions and theorems:

  1. (2\sqrt[3]{12} )\cdot (3\sqrt[3]{2} )  Given.
  2. (2\cdot 3) \cdot (\sqrt[3]{12} \cdot \sqrt[3]{2}  ) Commutative property/ Associative property.
  3. 6\cdot \sqrt[3]{24} Definition of cubic root/\sqrt[n]{a} = \sqrt[n]{b}/Result

After demonstrating the procedure by algebraic means, the expression (2\sqrt[3]{12} )\cdot (3\sqrt[3]{2} ) <em>is equivalent to</em> 6\cdot \sqrt[3]{24}.
