Question

Help, one question, I will fan and medal

Answer 1

\[\sqrt{10} \times \sqrt{8}\]

Answer 2

10^a *8^a

Answer 3

what? thats not a choice

Answer 4

it's a hint

Answer 5

you see sqrt(x) = x^(1/2)

Answer 6

10^.5 * 8^.5 your expression is equivelent to that

which is 80^.5

Answer 7

so \[4\sqrt{5}\] ?

Answer 8

sqrt(80) can be simplified further

Answer 9

yes

Answer 10

yay:)

Answer 11

sqrt(80) =
sqrt(16)*sqrt(5) =
4*sqrt(5)

Answer 12

\[\sqrt{80}= \sqrt{16 x 5 }= 4 \sqrt{5}\]

Answer 13

whenever in doubt

turn sqrt(a) int a^(1/2) and use the exponent properties and rules :)
