With some manipulation, the Rydberg equation can be rewritten in the form E=constant×(1nf2−1ni2)

which allows you to calculate the energy of the emitted light. Express this constant in terms of the constants h, c, and RH using relationships between wavelength and energy as well as the Rydberg equation from the introduction.

Express the constant in terms of h and c, and RH.

Please help me with this question?
