Question

multiply and simplify: sq rt 7x ((sq rt x)-7sq rt. 7)

Answer 1

sqrt(7)*(sqrt(x)-7*sqrt(7))


sqrt(7)*sqrt(x)-sqrt(7)*7*sqrt(7)


sqrt(7*x)-7*sqrt(7*7)


sqrt(7x)-7*sqrt(7^2)


I'll let you finish

Answer 2

the first part of problem is sq rt 7x. What did you do with the x?

Answer 3

oh didn't see it there, let me fix it, one sec

Answer 4

is it x* sq rt. 7-49*sq rt. x

Answer 5

sqrt(7x)*(sqrt(x)-7*sqrt(7))


sqrt(7x)*sqrt(x)-sqrt(7x)*7*sqrt(7)


sqrt(7*x*x)-7*sqrt(7x*7)


sqrt(7x^2)-7*sqrt(7^2*x)

Answer 6

again I'll let you finish

Answer 7

is it x*sq rt 7-49x

Answer 8

not quite

Answer 9

sq rt 7-49*sq rt x?

Answer 10

closer, but it's really

x*sqrt(7)-49*sqrt(x)

Answer 11

oh I have my last x written on my paper as sq rt but didn't type it that way. thanks
