See a solution process below:

Explanation:

Using the PEDMAS method, process the operation within the Parenthesis first:

#10^2 -: (color(red)(5) xx color(red)(4)) + (color(blue)(2) xx color(blue)(2)) => 10^2 -: 20 + 4#

Next, execute the Exponent operations:

#10^color(red)(2) -: 20 + 4 => 100 -: 20 + 4#

Then, execute the Division operation:

#color(red)(100) -: color(red)(20) + 4 => 5 + 4#

Now, execute the Addition operation giving:

#5 + 4 => 9#
