Use the PEMDAS method.

PEMDAS stands for:

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

We have a pair of parentheses, so let's solve that:

#60+5-4=61#

We now have #5cdot(61)^2#. We also have exponents and multiplication, so let's solve those in order:

#61^2=3721#
#5*3721=18,605#

Our answer is 18,605.
