Fill in the blank boxes with suitable numbers.

Here are the solutions to the problems using the laws of indices.

3. Fill in the blank boxes with suitable numbers.

a)
The central value is $5^{20}$. We use the rule $a^m \times a^n = a^{m+n}$.

• Top box: $5^6 \times 5^2 \times 5^8 \times 5^{\boxed{4}} = 5^{6+2+8+4} = 5^{20}$
• Left box: $5^8 \times 5^{\boxed{12}} = 5^{8+12} = 5^{20}$
• Right box: $5^{15} \
