2 (a) Use your calculator to work out $$rac{29^7 - 4.6}{ ext{sqrt}(35) - 1.9}$$ Write down all the figures on your calculator display - Edexcel - GCSE Maths - Question 3 - 2019 - Paper 3

Using a calculator to compute the expression:

rac{29^7 - 4.6}{ ext{sqrt}(35) - 1.9}

Calculating values step-by-step:

1. First, calculate $29^7$:
   • $29^7 = 29 \times 29 \times 29 \times 29 \times 29 \times 29 \times 29 = 1977326743.$
2. Next, compute $ext{sqrt}(35)$:
   • $ext{sqrt}(35) \approx 5.916079.$
3. Now, substitute these values back into the expression:
   • $\frac{1977326743 - 4.6}{5.916079 - 1.9}$
4. This gives:
   • $\frac{1977326743 - 4.6}{4.016079} \approx \frac{1977326738.4}{4.016079} \approx 492816190.3.$
5. The calculator display will show approximately 492816190.3.
