Given:

The value of 173 - 102 + ((26)/(13))2 - 12 + 20 × 12 = ?

Formula used:

Follow the BODMAS rule (Bracket, Order, Division/Multiplication, Addition/Subtraction)

Calculation:

173 = 4913

102 = 100

(26 ÷ 13)2 = 22 = 4

20 × 12 = 240

⇒ 4913 - 100 + 4 - 12 + 240

⇒ 4913 - 100 - 8 + 240

⇒ 4913 + 132

⇒ 5045

∴ The correct answer is option (1).
