First we simplify the "B"rackets. (94) in the brackets becomes a 5. 7x54^2 Now we simplify the "E"xponents. 4^2 becomes 16. 7x516 Now we simplify "D"ivision. Oh, there's no division. 3516. And finally do the addition and subtraction. 3516=19. You can search our questions for the word BEDMAS to find other examples and explanations, but try your own question first to see if you can do it now. Cheers,
