Question

(75/3) X (72/12) X 8 to the square root of 256 divide by square root of 400X(square root of 121 minus square root of 16) X (square root of 144 divide by square root of 36) divide by 3to the square root of 27)

/ means divide by

Answer 1

Assuming X means times,
((75/3)(72/12)8^√256)/(400 (√121 - √16)(√144/36)/3√27)
Sorry, too many ambiguities. Are you sure the very last part is not cube root of 27?

Answer 2

306 000x(3)^1/2
