Answer:

66

Explanation:

#-2/3[-10+8-64]#

#-2/3[-2-64]#

#-2/3[-66]#

#(-2/3)xx(-66)#

But a minus times a minus is plus answer so we have:

#color(blue)(2/3xx66)#

But you can write #color(blue)(2/3xx66)" as "color(brown)( 2xx66/3)#

but #" "66/3=33#

so #color(brown)( 2xx66/3)" " # can be written as#" " 2xx33#

#" "2xx33=66#
