Since, 2520 = 2 x 2 x 2 x 3 x 3 x 5 x 7 = 23 x 32 x 5 x 7
Therefore, p = 2 and q = 5
p = 22.32.q2 (where q is a prime < 7) is the prime factorisation representation of ‘p’. What is the value of p?
A point P(3,−2) is reflected in the origin as P′. Point Q(−7,1) is reflected in the x- axis as Q′. Write down the co-ordinates of P′ and Q′.
Factorise 10pq + 9 + 6p + 15q and give the value of the expression for p = 3 and q = 2 [3 MARKS]
