Proof step 5 from proof isSquare-isSquare (previous step)

dec.scale % 2 = 0, isSquare(dec.int) ⊦ ∃ dec0. dec0 * dec0 = dec

User applied rule exists right

And obtained the following new goals

Proof step 6:
dec.scale % 2 = 0, isSquare(dec.int) ⊦ mkDecimal(sqrt(dec.int), dec.scale / 2) * mkDecimal(sqrt(dec.int), dec.scale / 2) = dec

Rule argument

pos: right 1 terms: mkDecimal(sqrt(dec.int), dec.scale / 2) abort: F discard: T computed: F

Additional information
