Answer:

#49#

Explanation:

When a number or a variable has an exponent, it means that that number/variable is multiplied by itself, that many times.

So here we have #7^2#

This means that #7# is multiplied by itself, one other time. So we could rewrite is as:

#7*7#

From here we solve:

#7*7#

#=49#
