The lowest elevation in the world is in the dead sea at 413 feet below sea level. the highest elevation in the world is mount everest at 29,035 feet above sea level. which integer best represents the elevation of the dead sea? a) -413 b) -29,035 c) 29,035 d) 413

A because the dead sea is at 413 so you know its not B or C because that is for mount Everest. its a because the dead sea is 413 below sea level so its a negative number. so its a -413

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

A= the square root of 3“if letters are anything like people, they’re all equal and deserve to be treated equally.”
