Answer 2

3

Explanation:

Consider nearby cubes:

3³ = 3·3·3 = 27

(∛34)³ = 34

3.5³ = 3.5·3.5·3.5 = 42.875

4³ = 4·4·4 = 64

The closest integer to ∛34 is 3.

Alternatively, your calculator can tell you the cube root of 34 is about 3.2396. Rounded to the nearest integer, that is 3.

Some calculators don't have a cube-root button, but they do have a y^x button, or an x^n (or simply ^) button. To use that to find the cube root, you compute 34^(1/3).

The first attachment shows the result of typing 34^(1/3) into a Google search box. The second attachment shows the use of the calculator x^y button (just left of the 0 button). Parentheses around the exponent are mandatory if you want the correct answer.
