Math Problem Statement

(2 ⋅ 3)^2 + 2^2 ⋅ 5 ⋅ 6 ÷ (2^3) ⋅ 2^0 + 3^3 ⋅ 4 ⋅ 5 ÷ (3 ⋅ 5)^2

Solution

In the image, the expression involves several powers, multiplications, and divisions. Let me transcribe it clearly:

(23)2+2256(23)20+3345÷(35)2(2 \cdot 3)^2 + 2^2 \cdot 5 \cdot \frac{6}{(2^3)} \cdot 2^0 + 3^3 \cdot 4 \cdot 5 \div (3 \cdot 5)^2

Let's break it down step by step:

Step 1: Solve each power and simplify constants

  1. (23)2=62=36(2 \cdot 3)^2 = 6^2 = 36
  2. 22=42^2 = 4
  3. 23=82^3 = 8, so 623=68=34\frac{6}{2^3} = \frac{6}{8} = \frac{3}{4}
  4. 20=12^0 = 1
  5. 33=273^3 = 27
  6. (35)2=(15)2=225(3 \cdot 5)^2 = (15)^2 = 225

Step 2: Substitute values into the expression

36+45341+2745÷22536 + 4 \cdot 5 \cdot \frac{3}{4} \cdot 1 + 27 \cdot 4 \cdot 5 \div 225

Step 3: Simplify each term

  1. 3636 (stays the same)
  2. 45341=53=154 \cdot 5 \cdot \frac{3}{4} \cdot 1 = 5 \cdot 3 = 15
  3. 2745÷225=2720225=540225=2.427 \cdot 4 \cdot 5 \div 225 = \frac{27 \cdot 20}{225} = \frac{540}{225} = 2.4

Step 4: Add everything up

36+15+2.4=53.436 + 15 + 2.4 = 53.4

So, the result of the entire expression is 53.4.
