Hi There!
--------------------------------------------
Remember to follow PEMDAS.
--------------------------------------------
Problem #1:
= (25 - 6.25) + (5 · 3)²
= (18.75) + (15)²
= 18.75 + 225
= 243.75
--------------------------------------------
Problem #2:
= (8 + 3)² + 10 · (-4)
= (11²) + 10 · (-4)
= 121 + 10 · (-4)
= 121 + (-40)
= 81
--------------------------------------------
Hope This Helps :)
