Simplify 81 to the power of -3 over 4 end exponent 81^3/4

A. fourth root of 81 to the power of -3 end exponent end root ^4SQRT81^-3

B. fraction numerator 1 over denominator(fourth root of 81)cubed end fraction 1/(^4SQRT81)^3

C. 1 over 27 1/27

D. -27

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

150.6

all i did was i multiplied 5.02 by 30
