Answer 2

ANSWER:- 1/2

Step-by-step explanation:

THERE ARE 2 METHODS OF SOLVING :-

1] Simplify normally

2] exponents laws

# 1st method

it can also be written as 2^4 x 2^-5= 2^4 x 1/2^5 [we reciprocated the 2nd term as powers was negitive]

16 x 1/32= 1/2

# 2nd method

by the laws of exponent m^n x m^k=m^k+n

=2^4+(-5)=2^-1

= again the power is negative so we will reciprocate

=1/2

I HOPE THIS WILL HELP!
