Question

4m times the square root of m times the square root of 5m

Answer 1

4m times sqrt 5

Answer 2

so the answer would be what

Answer 3

what is the complete equation?

Answer 4

\[4m \times \sqrt{5m} \times \sqrt{5m} = 4m \times \sqrt{5m}^{2} = 4m \times 5m = 9m\]Because\[\sqrt{a} \times \sqrt{a} = a ^{\frac{ 1 }{ 2 }} \times a ^{\frac{ 1 }{ 2 }} = a ^{\frac{ 1 }{ 2 } + \frac{ 1 }{ 2 }} = a ^{1} = a\]
