Answer:
B. 2^10
Step-by-step explanation:
2^3 is the same as 2 × 2 × 2 which equals 8, and 2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 which equals 128.
8 × 128 = 1,024
Now we just figure out which option also equals 1,024.
A. 2^-4 = 1/16 or 0.06
B. 2^10 = 1,024
C. 2^9 = 512
D. 2^21 = 2,097,152
Hope this helps :)
