1. 15) a x10^4 + a x10^2 = 24 240 where a is a number.
Work out a x10 ^4 x a x 10^ 2
[2 marks)
2. Well observe firstly that ax10^4 = 24x10^3 --> ax10^4 = 2.4x10^4 --> a=2.4

You can finish the question off.

I'm really confused with what you have done

The question says:

ax10^4 + ax10^2 = 24 240.

Method 1:

Observe ax10^2 = 240 --> 100a=240-->a=2.4 (or ax10^4 = 24000 --> a=2.4)

Method 2:

10,000a + 100a = 24240 --> 10,100a=24240 --> a=2.4

Method 3:

a(10^4) + a(10^2) = 10^2[a(10^2 + a) = 100(101)a = 24240 --> 101a=242.4-->a=2.4

Oh make sense now thank you soo much.
