Expert Solution & Answer

Chapter 3.1, Problem 48E

Solution

The error in the given calculation and correct it.

The given calculation has error in last step. The correct value of is x=3 .

Given:

The calculation

Concept Used:

The even inter root of a number is defined for positive values only that are greater than or equal to 0.

The odd integer root of all real numbers is defined.

Power of a power property: xab=xa⋅b

Exponent property, a−n=1an

The exponent form of the nth root of a number a is given by an=a1n

Calculation:

Note that the cube of 3 is 27, so cube root of 27 must be 3. So, the given calculation has an error in the last step. The correct calculation is shown below

x3=27x=273x=3

Therefore, the given calculation has an error in last step.
