Answer with explanation:
We have to find equivalent expression of
![\rightarrow4* \sqrt{9^{(1)/(2)}}* x\\\\\rightarrow4* (9^{(1)/(2)})^{(1)/(2)}}* x}\\\\\rightarrow 4 *{9^{(1)/(4)}}* x}\\\\\text{Used the Identity}(a^b)^m=a^(bm)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/kd6mcp6vrnjronymjxifqk77knfy1rwvfo.png)
Two expression are said to be equivalent, if we replace the variable by some constant value , the Numerical value of Original expression and the Numerical value of Equivalent expression are same.
