Q. Given x>0, the expression x4 is equivalent tox2xxx2xx
Question Prompt: Question prompt: What is the equivalent expression for x4 given x > 0?
Properties: Understand the properties of square roots and exponents.The square root of a number is the value that, when multiplied by itself, gives the original number. For any positive real number a, a2=a. This is because (a)2=a2, and since we are given that x > 0, we can apply this property directly.
Apply Property: Apply the property to the given expression.We have x4. According to the property from Step 1, this simplifies to x24 because the square root is the same as raising to the power of 21, and when we multiply the exponents, we get (4×21)=2.
Simplify Expression: Simplify the expression.Simplifying x(4/2) gives us x2. Since x is positive, we do not need to consider the absolute value, and we can directly state that x4=x2.
