Use the root function, which is the shifted function of the "x-superscript-y" key, located just below the "cos" key. For example, to calculate the 5th root of 32, press 32 [SHIFT] [x^y] 5 =
For cube roots, use the cube-root function in the MATH menu. For example, to calculate the cube root of 8, press MATH 4 8 =
For other roots (including cube root), use the xth-root function in the MATH menu. For example, to calculate the fifth root of 32, press 5 MATH 4 3 2 =
Use the nth-root function, which is the shifted function of the y^x key just above the divide key. For example, to calculate the 5th root of 32, press 32 2nd [xth-root] 5 =
Use the x-root function, which is the 2nd function of the y^x key located just above the divide key. For example, to find the cube root of 8, press 8 2nd x-root 3 =
You can calculate cube roots by using the cube root function (the 2nd-shift of the 0 key). You can calculate arbitrary roots by using the x-root function (the 2nd-shift of the y^x key, just above the divide key).
