√2/√10 = √(2/10) = √(1/5) = √(1x5/5x5) = (√5)/5
5*sqrt(5)/sqrt(2) = 5*sqrt(5/2) = 5*sqrt(2.5) = 7.91, approx.
2(q^2 - 5) or 2(q - the square root of 5)(q + the square root of 5)
square root of 20 = square root of 4 * square root of 5. square root of 4 = 2, so your answer is 2 square root of 5.

5/2=2.5*2=5
√2/√10 = √(2/10) = √(1/5) = √(1x5/5x5) = (√5)/5
5*sqrt(5)/sqrt(2) = 5*sqrt(5/2) = 5*sqrt(2.5) = 7.91, approx.
The question does not make clear what exactly is being sought. Is it ..... (the square root of 2) x 5 or ...... the square root of (2 x 5) The answer to the first is worked out as follows The square root of 2 = 1.4142 1.4142 x 5 = 7.071 The answer to the second is worked out as follows 2 x 5 = 10 The square root of 10 = 3.1623
2(q^2 - 5) or 2(q - the square root of 5)(q + the square root of 5)
square root of 20 = square root of 4 * square root of 5. square root of 4 = 2, so your answer is 2 square root of 5.
the square root of 2: 1.000 the square root of 5: 2.236 hope it helps
The square root of fraction 20 over 25: = √20 ...√25 = √4(5) ......5 = 2√5 .....5 or 2 square root of 5 over 5
