You are trying to make

1-3x

equal to something.

0.97

is sensible as this means

x = 0.01

.

Remember the binomial expansion of

(1+y)^n

is only valid for

|y| < 1

so you need to choose x carefully.

But if i chose something smaller than x=0.01 would i still get marks?

0.001 ?

Bad choice.

\displaystyle 97 = \frac{97000}{997} \times (1-3 \times 0.001)

Good luck applying the indices!
