Sagot :
[tex](5\sqrt{2})^2=5^2\cdot (\sqrt{2})^2= 25 \cdot \sqrt{4}=25\cdot 2 \to \boxed{50}[/tex]
[tex](5 \sqrt{2} )^{2} [/tex]
- this expression means the value obtained when the product of 5 and the square root of 2 is raised to the power of 2.
[tex](5 \sqrt{2})^{2} [/tex] = 5² x [tex] \sqrt{2}^{2} [/tex] = 25 x 2 = 50
