\( 5+\sqrt{36}-1= \)
Both square roots and exponents have equal priority in PEMDAS! Calculate them from left to right: first and , then .
Yes, absolutely! You can calculate . This gives the same result as , so use whichever method feels easier!
The large result comes from ! Remember that squaring makes numbers much bigger, and then multiplying by 6 makes it even larger. The square roots only contribute 6 to the total.
That's wrong! The expression means , not . Always calculate exponents first before any other operations.
Break it into parts: , then , then , finally . Each step should be simple mental math!
