50 points and brainliest (3^8 x 2^-5 x 9^0) ^-2 x (2^-2 / 3^3) ^4 x 3^28 write your answer in simplified form. show all the steps

(3^8 *2^-5 *9^0)^-2 *  (2^-2/3^3)^4 * 3^28 =

(6561 * 0.03125 * 1)^-2 * (0.25/27)^4 * 2.287679245x10^13 =

0.0000237881 * 0.00000000073503 * 2.287679245x10^13 =

0.40000008, round to 0.4

all but the second one

step-by-step explanation:

cuz that one goes over 180

mark brainliest

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
