Question

If a and b are positive integers and (2a)b = 23, what is the value of 2a 2b ?

Answer 1

Answer:

(2^a)^b = 23

#2^ab = 23

2 raised to any integer power can't be an odd number .

i think it should be (2^a)^b = 2^3

=>2^ab = 2^3

ab = 3

if a = 1 then b = 3 or if a=3 then b=1

2^a*2^b = 2^(a+b)  

= 2^4 = 16

The final answer is 16....
