d)29-[16+3.(51-49)]

=29-[16+3.2]

=29-[16+6]

=29-22

=7

e)295-(31-2^2 .5)^2

=295-(31-4.5)^2

=295-(31-20)^2

=295-11^2

=295-121

=174

f)7^18:7^16+2^2 .3^3

=7^2+4.27

=49+108

=157

g)59:57+12.3+70

=59/57+36+70

=2111/57+70

=6107/57

h)59:57+70:14-20

=59/57+5-20

=344/57-20

=-796/57

k)47-[(45.2^4-5^2 .12):14]

=47-[(45.16-25.12):14]

=47-(420:14)

=47-30

=17
