The answer is #7^6# or 117,649.

Explanation:

Here are some rules when working with exponents(powers):

#a^m*a^n = a^(m+n)#
#a^m-a^n = a^(m-n)#
#a^0 = 1#

where, #a# is any natural number(1,2,3,4...) and #m and n# are whole numbers(0,1,2,3,4.....) or fractions.

So, in this question,

#(7^5*7^3)/7^2 = 7^(5+3-2) = 7^6 = 117,649#

#7^6 = 117649#

Explanation:

Note that #" "7^5xx7^3" " =" " 7^(5+3)" "=" "7^8#

But #" "7^8# is the same as #7^6xx7^2#

Write #" "(7^5xx7^3)/7^2" as "(7^6xx7^2)/7^2#

#7^6xx7^2/7^2" "=" "7^6xx1" "=" "7^6##
