#ab # means product of #a# and #b#, not merely placing the given digits 3 and 4.

# therefore ab = 12#

K= ab+c/2

a=3
b=4
c=6

#K = ab + c/2 #

Apply BODMAS rule:

# K = 3\times 4 + 6/2#

# K = 12 + 3#

# K =15#

Value of #ab = 12#

In the expression, #ab # means product of #a# and #b#, not merely positioning the given digits 3 and 4.
