Answer:
The matches are not given but these can be written in exponent form like below:
1. 256 can be written as [tex]16\times16=16^{2}[/tex]
2. 9 = [tex]3\times3=3^{2}[/tex]
3. 16 = [tex]4\times4=4^{2}[/tex]
4. 25 = [tex]5\times5=5^{2}[/tex]
5. 225 = [tex]15\times15=15^{2}[/tex]
6. 196 = [tex]14\times14=14^{2}[/tex]
