ITPEC IP October 2025 Question 4
ITPEC IP October 2025 — Question 4 of 100
M multiplied by 10³ is G — mega is 10⁶ and giga is 10⁹.
Multiplying a quantity expressed in mega-units by 10³ increases its prefix exponent from 6 to 9: 10⁶ × 10³ = 10⁹. Therefore 1,000 M equals 1 G. The nearby prefix tera is 10¹².
Answer (b)
Why not others:
- (a) gives 10⁹ × 10⁶ = 10¹⁵, which is peta, not tera
- (c) gives 10⁶ × 10⁶ = 10¹², which is tera, not giga
- (d) claims increasing tera produces the smaller giga prefix
Key rule: SI prefixes advance by powers of 1,000 here: mega 10⁶, giga 10⁹, tera 10¹², peta 10¹⁵.
