Question

Which of the following expressions are equivalent? Justify your reasoning.
(͜͡a). 4√x³
(͜͡b). 1/(x⁻¹)
(͜͡c). 10√x⁵•x⁴•x²
(͜͡d). x⅓* x⅓* x⅓

Answer 1

b and d are equal:
1/x^-1 is just x because you have 1/1/x which is x

x^1/3*x^1/3*x^1/3 is again just x because you have (x^1/3)^3 which is x^3/3 which is just x

a is not equal to anything else and c is not equal to anything else
