Answer 1

c)[(2^3-4)^2+3^2]:5
=[(8-4)^2+9]:5
=(4^2+9):5
=(16+9):5
=25:5
=5
d)[(2^2x5+1):3+1]^2-3^2x7
=[(4x5+1):3+1]^2-9x7
=(21:3+1)^2-63
=8^2-63
=64-63
=1
e)(6^3:2^2:3-4^2)^5-3^3
=(216:4:3-16)^5-27
=(18-16)^5-27
=2^5-27
=32-27
=5
f)[(13^2-12^2)^2-7^2]:24
=[(169-144)^2-49]:24
=(25^2-49):24
=576:24
=24
