Question

(2/-3)power -4 is equal to option a. 81/16 b. -81/16 please answer me with solution​

Answer 1

Answer:

2/-3 power -4

first we will change into positive exponent by using law i.e a/1 power -a =a/1 power a

bu using that law 2/-3 power -4

=-3/2⁴

minus sign will come with 3 because while we write answer then we write minus in numerator

now next step ,solve power is 4 so we will multiply -3/2⁴ 4 times

=-3/2*-3/2*-3/2*-3/2=81/16

we multiply numerator with numerator and denominator with denominator if they are cutting then cut them and follw the step of multiplying numerator with numerator and denominator with denominator

hence the answer is a part i.e 81/16

81/16
