45 = 9 * 5
81 = 9 * 9
sqrt ( 45 ) / sqrt ( 81 ) =
sqrt ( 9 ) * sqrt ( 5 ) / sqrt ( 9 ) * sqrt ( 9 ) =
sqrt ( 5 ) / sqrt ( 9 ) =
sqrt ( 5 ) / 3
7sqrt ( 3 ) / sqrt ( 5 )
Cannot be simplified becouse 3 and 5 is primes numbers.
sqrt(7)/sqrt(8) * sqrt(24)/sqrt(49) =
[sqrt(7)/sqrt(8)] * [ sqrt(3) * sqrt(8) / sqrt(7) * sqrt(7) ] =
sqrt ( 3 / 7 )
Thanks for the answers but I must show the work for each problem.
Can someone please help now that I finally submitted the square root correctly,thanks to drwls, and
Ms. Sue.
Thank you
The slash (/) line represents that the number is a fraction.
divide:
sqrt45 / sqrt81 =
simplify:
7sqrt3 / sqrt5 =
Multiply:
sqrt7/sqrt8 X sqrt24/sqrt49 =
