A student answered the following skilltesting question to try and win a prize:
(4)^3(2)^4/2^2+5^2*7^0
The students answer was 5. Did the student win the prize?
I couldn’t seem to figure out how to answer this question. I got the answer 13, but my answer sheet said 43. I’m not very good with exponents, so could someone help me through this?

adding some spaces for readability,
(4)^3  (2)^4 / 2^2 + 5^2 * 7^0
do powers first:
64  16 / 4 + 25 * 1
now multiply or divide:
64  4 + 25
now add and subtract:
68+25 = 43
