p = 22.32.q2 (where q is a prime < 7) is the prime factorisation representation of ‘p’. What is the value of p?
Can’t say
p = 36
p = 900
p = 700
So p is 5 and the number is 900.
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′.
