90 ÷ [10 + (3^2 -4)]

(I don't need the answer, but I would just like to know how to figure out the answer by myself)

Answer 1

Well follow PEMDAS
So first solve in the parenthesis
(3^2-4) now we focus on E for exponents
3 to the second power is 3 times 3 9
9-4=5
Now we solve brackets still using the PEMDAS 10+9=19 now the last step 90 divided by 19= 4.736 . I hope i did this right its like 10 am and I'm rushing.

Answer 2

Wait... nvm I made a mistake the answer is 6

Answer 3

I went wrong at 10+9 because 9-4 is 5 and I should have added 10+5 anyway hope it helps

Answer 4

90 ÷ [10 + (3^2 -4)]
= 90 ÷ [10 + (9 -4)]
= 90 ÷ [10 + (5)]
= 90 ÷ [15]
= 6
