Question

p = $2^2$.$3^2$.$q^2$ (where q is a prime $<$ 7) is the prime factorisation representation of ‘p’. What is the value of p?

• A. p = 700
• B. p = 300
• C. p = 900
• D. p = 500

Answer 1

The correct option is C

p = 900

Prime numbers below 7 are 2, 3, and 5.
2 and 3 are already used, hence q = 5.
So, p = $2^2$.$3^2$.$5^2$ = 900.
