Math Problem Statement

Rewrite cube root of, 128, end cube root 3

128 ​ in simplest form.

Solution

To rewrite 1283\sqrt[3]{128} (the cube root of 128) in its simplest form, follow these steps:

  1. Prime Factorization of 128: 128=27128 = 2^7

  2. Cube Roots: We look for groups of three identical factors, as that's what a cube root simplifies: [ \sqrt[3]{2^7} = \sqrt[3]{2^6 \times 2} = 2^2 \times \sqrt[3]{2} = 4\sqrt[3]{2} ]

So, 1283=423\sqrt[3]{128} = 4\sqrt[3]{2}.
