Math Problem Statement
cube root of 1600 by prime factorization
Solution
To find the cube root of 1600 using prime factorization, follow these steps:
Step 1: Prime Factorization of 1600
First, break 1600 into its prime factors:
800 \div 2 = 400 \\ 400 \div 2 = 200 \\ 200 \div 2 = 100 \\ 100 \div 2 = 50 \\ 50 \div 2 = 25 \\ 25 \div 5 = 5 \\ 5 \div 5 = 1$$ The prime factorization of 1600 is: $$1600 = 2^6 \times 5^2$$ ### Step 2: Cube Root of Each Factor To find the cube root, we need to divide the exponents of the prime factors by 3: $$\text{Cube root of } 1600 = \sqrt[3]{2^6 \times 5^2} = 2^{\frac{6}{3}} \times 5^{\frac{2}{3}} = 2^2 \times 5^{\frac{2}{3}}$$ This simplifies to: $$\text{Cube root of } 1600 = 4 \times \sqrt[3]{25}$$ ### Final Answer The cube root of 1600 is $$4 \times \sqrt[3]{25}$$.
