We must know that we do whatever is inside the parentheses first. The square root of 64 is 8 (8 x 8 equals 64.), 4 squared is 16 (4x4), these |randomnumberinhere| are called absolute value, anything inside "randomnumberinhere" will become a positive regardless if it's a negative. 8-16 equals -8 and the bottom would be 4. -8 divided by 4 equals -2. 10-26 is equal to -16. -16 divided by -2 is equal to 8.
Your answer is 8.
