Both answers is correct but you can simplify answer 1.
sqrt ( 280 x ^ 6 ) / sqrt ( 7 x ) =
sqrt ( 280 x ^ 6 / 7 x ) =
sqrt [ ( 280 / 7 ) * x ^ 6 / x ] =
sqrt ( 40 * x ^ 5 ) =
sqrt ( 40 ) * sqrt ( x ^ 5 ) =
sqrt ( 4 * 10 ) * sqrt ( x ^ 5 ) =
sqrt ( 4 ) * sqrt ( 10 ) * sqrt ( x ^ 5 ) =
2 * sqrt ( 10 ) * sqrt ( x ^ 5 ) =
2 * sqrt ( 10 ) * x ^ ( 5 / 2 )
Could someone just double check my work
sqrt280x^6/sqrt7x
I got 2x^3 sqrt10\sqrtx
Also 1/5(30y+40)+2/3(9y-27)=18
I got 7/3

If you'll allow one more step,
2x^2 sqrt(10x)
2x^2 sqrt(10x)
1. 2x sqrt(10x^3)
2. 7/3
2. 7/3
By the way, 2x^3 sqrt(10/x) is also correct. So, good work, I think.
