The exponent form of 343 using 7 as base will be [tex]7^3[/tex].
Given value is 343.
We have to express it with an exponent.
An exponent refers to the number of times a number is multiplied by itself.
Now, the factors of 343 is ,
[tex]343=7\times7\times7[/tex]
Since the base is same ( 7 ) here, so applying the identity [tex]x^{m} \times x^{n} =x^{m+n}[/tex]
So,
[tex]343=7^{1+1+1}[/tex]
[tex]343=7^{3}[/tex]
Hence the exponent form of 343 is [tex]7^3[/tex].
