Original question and givens

The real matrix M=[[-2], [0], [2]] is displayed as nested rows. Find Mᵀ as a nested list of rows.

  • G001 — The real matrix M=[[-2], [0], [2]] is displayed as nested rows. Find Mᵀ as a nested list of rows.

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.

Step-by-step derivation

S001 · implies

Before

source roles = [qf-matrix-transpose, matrix_transpose, reals, []]

After

derived = [[nested_ROW_matrix]]

Conditions: none

MOD25 uses LOCAL hyphens/named domains,legacy matrices underscores/reals;BASE logic acquires no domain/op.Output tuples,matrices,numeric fields and fraction texts follow THIS source,not a universal/1 rule.Retain originals/English/AST/status.

Step identifiers and dependencies

Rule: R65_SOURCE_bank_keys_operation_domain_ordered_output_roles · Uses: G001

S002 · implies

Before

source roles = [M ORIGINAL, [[-2], [0], [2]]]

After

derived = [3, 1]

Conditions: none

THIS bank allows1..5 by1..5 matrices,not the R64 2×2 restriction.Type EVERY raw SAFE cell,including unused shape/entry cells.Keep original row order.

Step identifiers and dependencies

Rule: Matrix_RAW_rectangular_1to5_ALL_SAFE_entries_even_unused · Uses: G001, S001

S003 · implies

Before

source roles = [1, 1, -2]

After

derived = [1, 1, -2]

Conditions: none

Move EVERY original(i,j)to(j,i),not row reversal or matrix inversion.Rectangular dimensions exchange.

Step identifiers and dependencies

Rule: Matrix_TRANSPOSE_EACH_original_i_j_moves_to_j_i · Uses: G001, S002

S004 · implies

Before

source roles = [2, 1, 0]

After

derived = [1, 2, 0]

Conditions: none

Move EVERY original(i,j)to(j,i),not row reversal or matrix inversion.Rectangular dimensions exchange.

Step identifiers and dependencies

Rule: Matrix_TRANSPOSE_EACH_original_i_j_moves_to_j_i · Uses: G001, S003

S005 · implies

Before

source roles = [3, 1, 2]

After

derived = [1, 3, 2]

Conditions: none

Move EVERY original(i,j)to(j,i),not row reversal or matrix inversion.Rectangular dimensions exchange.

Step identifiers and dependencies

Rule: Matrix_TRANSPOSE_EACH_original_i_j_moves_to_j_i · Uses: G001, S004

Reverse checks

  • S005 · premise_and_result_audit — Reverse-check ORIGINAL data,types,ordered roles,domain and premises;the conclusion need not uniquely recover its premises.Keep finite source candidates,independent review,formal proof and publication separate.
  • S004 · premise_and_result_audit — Reverse-check ORIGINAL data,types,ordered roles,domain and premises;the conclusion need not uniquely recover its premises.Keep finite source candidates,independent review,formal proof and publication separate.
  • S003 · premise_and_result_audit — Reverse-check ORIGINAL data,types,ordered roles,domain and premises;the conclusion need not uniquely recover its premises.Keep finite source candidates,independent review,formal proof and publication separate.

Result

[[-2, 0, 2]]

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
