90=k\times 1600

Kalkulahin ang 40 sa power ng 2 at kunin ang 1600.

k\times 1600=90

Pagpalitin ang magkabilang panig para nasa kaliwang bahagi ang lahat ng variable na term.

k=\frac{90}{1600}

I-divide ang magkabilang dulo ng equation gamit ang 1600.

k=\frac{9}{160}

Bawasan ang fraction \frac{90}{1600} sa pinakamabababang term sa pamamagitan ng pag-extract at pag-cancel out sa 10.
