No. Although both 5252 and (−5)2(−5)2 are 2525, the radical symbol implies only a nonnegative root, the principal square root. The principal square root of 25 is √25=525=5.Example: Evaluating Square Roots Evaluate each expression. √100100 √√1616 √25+14425+144 √49−√8149...
Because when you square a number, you will always get a positive result, so the principal square root of (b2)2(b2)2 will always be non-negative. One tip for knowing when to apply the absolute value after simplifying any even indexed root is to look at the final exponent on your ...

49 - 224 = -175Applying the quadratic formula : 7±√ -175 w = ——— 8In the set of real numbers, negative numbers do not have square roots. A new set of numbers, called complex, was invented so that negative numbers would have a square root. These numbers are written (a+b*i)...
The square root of a number is really easy to find. Let's remember first that finding the square root of a number is the opposite of finding the exponent of a number. Moreover, we are only going to deal with positive square roots, a negative square root
Simplify the expression: ln (x^2 square root{4-x^2}) Explain what the sign of the answer is when a negative number has an exponent. For example, is (-4)^2 equal to +16 or -16? Simplify (x - 5)^2 Write the following using exponents: (-4)(-4). How do you simplify exponent...
