Answer:
128 calories
Step-by-step explanation:
Remember that an exponent represents multiplying a number repeatedly by itself. For example, using this situation, [tex]2^7[/tex] would represent 2 multiplied by itself seven times:
2 x 2 x 2 x 2 x 2 x 2 x 2
notice that there are 7 2's multiplied by each other ^^
if you are doing this without a calculator, its easiest to start one at a time
2 x 2 = 4
now there are 5 2's left
4 x 2 = 8
there are 4 2's left
8 x 2 = 16
there are 3 2's left
16 x 2 = 32
there are 2 2's left
32 x 2 = 64
there is one 2 left
64 x 2 = 128
so [tex]2^7[/tex] = 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128
I hope that helps :)
