Cube Root of 1331 By Prime Facrtorization
Use the following steps to find the cube root of 1331
Step 1: Determine the prime factorization of 1331 = 11 Γ 11 Γ 11
Step 2: Group the prime factors of 1331 in groups of three each. 1331 = (11 Γ 11 Γ 11)
Step 3: Use the law of exponents: 1331 = (113)1/3
Therefore, the cube root of 1331 by prime factorization is (11 Γ 11 Γ 11 )1/3 = 11.
Cube Root of 1331 By Long Division Method
Use the following steps to find the cube root of 1331 by Long Division Method
Step 1: Begin by grouping the digits of the number 1331 in sets of three, starting from the right
Step 2: Find a number whose cube is less than or equal to the leftmost group. In this case, the cube of 1 is 1, which is less than 1331.
Step 3: Write the cube root (1) above the division symbol and subtract the cube (1) from the leftmost group
Step 4: Bring down the next group of digits to the right of the remainder
Step 5: Double the current quotient (1) and write it next to the previous quotient
Step 6: Guess a digit to add to the current quotient, which, when multiplied by the doubled quotient, gives a result less than or equal to the current remainder. In this case, the closest digit is 4 because 204 Γ 4 = 816, which is less than 831.
Step 7: Write the guessed digit (4) above the division symbol and multiply it by the doubled quotient
Step 8: Subtract the result from the previous remainder and bring down the next group of digits:
Step 9: Repeat steps 5 to 8 until you have obtained the desired level of precision or until the remainder becomes zero.
Continue the process until you reach the desired level of precision or until the remainder becomes zero. In this case, the cube root of 1331 is 11.
So, using the division method, you find that the cube root of 1331 is 11.
Is the Cube Root of 1331 Irrational?
