Written and checked by us, not taken from the Pearson paper. Tap "Worked answer" to see every step.

1. Indices and Standard Form

   Work out \((7\times10^{5})\times(6\times10^{-2})\), giving your answer in standard form.

   Worked answer

   1. Multiply the numbers: \(7\times6=42\).
   2. Add the powers: \(10^{5+(-2)}=10^{3}\).
   3. \(42\times10^3=4.2\times10^{4}\).

   Answer: \(4.2\times10^{4}\)

2. HCF, LCM and Prime Factors

   Write 1260 as a product of prime factors in index form.

   Worked answer

   1. \(1260=2\times630=2\times2\times315\).
   2. \(315=3\times105=3\times3\times35=3\times3\times5\times7\).
   3. So \(1260=2^2\times3^2\times5\times7\).

   Answer: \(2^2\times3^2\times5\times7\)

3. Quadratic Equations

   The product of two consecutive positive integers is 132. Find them.

   Worked answer

   1. \(n(n+1)=132\), so \(n^2+n-132=0\).
   2. \((n+12)(n-11)=0\).
   3. \(n=11\) (positive), so 11 and 12.

   Answer: 11 and 12
