Also, I wasn't initially sure where in PEMDAS the square root should fall. I looked it up, and was reminded that square root is the same as a fractional exponent. 64^1/2. That meant that I did the exponent first, then did the divisions and multiplications from left to right. I also knew that division by a fraction could be replaced by multiplication by the inverted fraction.
I think you're right. At first I wanted to cancel out the 2's, but then I remembered that I had to work from left to right after taking the square root of 64 which is 8. Then I changed the division sign to a multiply sign and inverted the 1/2 fraction making it a 2. That left 8 * 2 * 2 which is 32.

√64 ÷ 1/2 ×2 = √(8)^2 ÷ 1/2×2 =8×2/1×2 = 8×2×2 = 32
Hooray! I got one right!
256 - 16 😊😊
256 ose 16 😊😊
If you used the correct equation, ie using brackets, there could be a correct answer.
32 😂😂😂 😂😂

32, straightforward mental arithmetic.
