I think the awkward science is quite amusing to me
7√7
using the ' rule of radicals '
• √a × √b ⇔ √ab
simplifying the radicals
√28 = √(4 × 7 ) = √4 × √7 = 2√7
√63 = √(9 × 7) =√9 × √7 = 3√7
√112 = √(16 × 7 ) = √16 × √7 = 4√7
substituting into the expression
3(2√7) - 5(3√7) + 4(4√7) = 6√7 - 15√7 + 16√7 = 7√7
Yes it is because 1/4 + 1/4 =2/4 and 2/4 equals 1/2
All you have to do is divide 500 by 3.
500 divided by 3 is 166.666667
I hope this helps:)
