Answer:
[tex] \sf p = \dfrac{i}{rt} [/tex]
Step-by-step explanation:
Solve for p:
[tex] \longrightarrow [/tex] i = prt
i = prt is equivalent to prt = i:
[tex] \longrightarrow [/tex] prt = i
Divide both sides by rt:
[tex] \longrightarrow [/tex] [tex] \sf \dfrac{prt}{rt} = \dfrac{i}{rt} [/tex]
[tex] \sf \dfrac{prt}{rt} = p: [/tex]
[tex] \longrightarrow [/tex] [tex] \sf p = \dfrac{i}{rt} [/tex]
