Add 31−−√+31−−√
To add the expression √31 + √31, we can simplify it by combining like terms.
√31 + √31= 2√31
So, the sum of √31 + √31 is equal to 2√31.
Adding 31−−√ and 31−−√ together would involve adding the whole numbers and adding the square root terms separately:
31−−√ + 31−−√
= (31 + 31) + (−−√ + −−√)
= 62 + 2(−−√)
= 62 −−√
To simplify the expression 31-√31-√, we can follow these steps:
Step 1: Determine the value of √31
√31 is an irrational number and cannot be simplified further, so we leave it as it is.
Step 2: Substitute the value of √31 back into the expression
31-√31 -√ becomes 31 - √31.
And there you have it, the simplified expression is 31 - √31.
