Answer:

Option 2 -
(2^2* 2^3)/(2^4)=2^(1)

Explanation:

Given : Expression '2 power 2 multiplied by 2 power 3 over 2 power 4'.

To find : What is the simplified expression ?

Solution :

Writing expression in numeric form,

'2 power 2 multiplied by 2 power 3 over 2 power 4',

i.e.
(2^2* 2^3)/(2^4)

Solving the expression,

As,
x^a* x^b=x^(a+b)


(2^2* 2^3)/(2^4)=(2^(2+3))/(2^4)


(2^2* 2^3)/(2^4)=(2^(5))/(2^4)

As,
\farc{x^a}{x^b}=x^(a-b)


(2^2* 2^3)/(2^4)=2^(5-4)


(2^2* 2^3)/(2^4)=2^(1)


(2^2* 2^3)/(2^4)=1

Therefore, The option 2 is correct.
