Quick guide

How to use this calculator

  1. Choose a calculation mode when the page offers more than one relationship.
  2. Enter the labelled known values.
  3. Read the primary result and use the check or equivalent form to verify its meaning.

Calculation method

Apply the exponent, root, or logarithm relationship

For a·root_n(bx+c)+d=e, isolate the root, raise to n, solve, then check.

The calculator checks real-number domains, zero denominators, unsupported powers, and finite-range limits before reporting a result.

Worked example

Worked example

√(x+1)=3 gives x=8.

For a·root_n(bx+c)+d=e, isolate the root, raise to n, solve, then check.

Supported inputs

Precision and limits

Real-number scope

These calculators return real results. Complex branches are handled by the separate complex-number calculators.

Numerical range

Inputs may be zero or have absolute magnitude from 1e-100 through 1e100. Exact integer radical simplification uses its narrower disclosed bound.

Precision

Numerical functions use double-precision arithmetic and normally display 12 significant digits. Symbolic labels are exact only where explicitly stated.
