Answer with explanation:
We have to find equivalent expression of
[tex]\rightarrow4\times \sqrt{9^{\frac{1}{2}}}\times x\\\\\rightarrow4\times (9^{\frac{1}{2}})^{\frac{1}{2}}}\times x}\\\\\rightarrow 4 \times{9^{\frac{1}{4}}}\times x}\\\\\text{Used the Identity}(a^b)^m=a^{bm}[/tex]
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.
