#14#

Recall PEMDAS

Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction. This is the order we simplify in.

We have no parenthesis, so we can simplify the exponents to get

#64-20div2xx5#

Recall that when we do PEMDAS, we work left to right. This means we do the division first (#20div2#) to get

#64-10xx5#

Multiplication of #10# and #5# is next, and we get

#64-50#, which simplifies to

#14#

Hope this helps!
