Please help me answer and explain number 55
melamori03 [73]

Answer:

D

Step-by-step explanation:

An operation of two real numbers is defined by the rule

a\bigotimes b=b^a+2ab

Calculate 2\bigotimes (1\bigotimes 3). First evaluate the expression in brackets:

1\bigotimes 3=1^3+2\cdot 1\cdot 3=1+6=7

Now,

2\bigotimes (1\bigotimes 3)=2\bigotimes 7=2^7+2\cdot 2\cdot 7=128+28=156
