Answer :

Certainly! Let's solve the problem step-by-step for each pair and identify the bigger number in each case.

### Part (a) [tex]$2^5$[/tex] and [tex]$5^2$[/tex]

1. Calculate [tex]$2^5$[/tex]:
[tex]\[ 2^5 = 2 \times 2 \times 2 \times 2 \times 2 = 32 \][/tex]

2. Calculate [tex]$5^2$[/tex]:
[tex]\[ 5^2 = 5 \times 5 = 25 \][/tex]

3. Compare the results:
[tex]\[ 32 \quad \text{and} \quad 25 \][/tex]
Clearly, [tex]$32$[/tex] is greater than [tex]$25$[/tex].

Therefore, the bigger number between [tex]\(2^5\)[/tex] and [tex]\(5^2\)[/tex] is [tex]\(32\)[/tex].

### Part (b) [tex]$3^4$[/tex] and [tex]$4^3$[/tex]

1. Calculate [tex]$3^4$[/tex]:
[tex]\[ 3^4 = 3 \times 3 \times 3 \times 3 = 81 \][/tex]

2. Calculate [tex]$4^3$[/tex]:
[tex]\[ 4^3 = 4 \times 4 \times 4 = 64 \][/tex]

3. Compare the results:
[tex]\[ 81 \quad \text{and} \quad 64 \][/tex]
Clearly, [tex]$81$[/tex] is greater than [tex]$64$[/tex].

Therefore, the bigger number between [tex]\(3^4\)[/tex] and [tex]\(4^3\)[/tex] is [tex]\(81\)[/tex].

### Summary of Results:

- For [tex]\(2^5\)[/tex] and [tex]\(5^2\)[/tex], the bigger number is [tex]\(32\)[/tex].
- For [tex]\(3^4\)[/tex] and [tex]\(4^3\)[/tex], the bigger number is [tex]\(81\)[/tex].

Thus, the bigger numbers in each pair are [tex]\(32\)[/tex] and [tex]\(81\)[/tex], respectively.
