In this question we have to convert all the question back into the square root.
Now, Calculate the (a) part of the question i.e.
(a) [tex]7\sqrt{10}[/tex] ,Calculate it further,
[tex]\bold{7\sqrt{10} =\sqrt{7^{2} \times 10 } =\sqrt{490}}[/tex]
Now, calculate the (b) part of the question i.e.
[tex](b)\;6\sqrt{x}[/tex] calculate it further,
[tex]\bold{6\sqrt{x} =\sqrt{6^{2} \times x } =\sqrt{36x}}[/tex]
Now, calculate the (c) part of the question i.e.
[tex](c)\:3\sqrt{2a}[/tex] calculate it further,
[tex]\bold{3\sqrt{2} =\sqrt{3^{2} \times 2a } =\sqrt{18a}}[/tex]
Now, calculate the (d) part of the question i.e.
[tex](d)\:5\sqrt{3}[/tex], calculate it further,
[tex]\bold{5\sqrt{3} =\sqrt{5^{2} \times 3 } =\sqrt{75}}[/tex]
And, calculate the (e) part of the question i.e.
[tex](e) \: 10\sqrt{y}[/tex] , calculate it further,
[tex]\bold{10\sqrt{y} =\sqrt{10^{2} \times y } =\sqrt{100y}}[/tex]
