@Ziva_vibes3y or the short way: 144 / 36 => 4
Because squaring the entire equation enclosed in the parentheses has the effect of negating the sqrt components (so you can just ignore them).
@Ziva_vibes3y Interesting thing about this equation is that you can come to the correct answer in a couple of ways. The long way:
(sqrt[144] / sqrt[36])^2 =>
(12 / 6)^2 =>
2^2 =>
4
@farman4x Order Of Operations:
sqrt[144] + (sqrt[36] / sqrt[9]) x sqrt[64] =>
sqrt[144] + (6 / 3 ) x sqrt[64] =>
sqrt[144] + 2 x sqrt[64] =>
12 + 2 x 8 =>
12 + 16 =>
28
Took me at least a hundred times longer to type all this out than it did for me to initially solve it in my head.
@BaileyBrine@Rainmaker1973 Designed and built my first (multi-processor) computer (out of chips and breadboards) in ‘76 and wrote the operating system, but apparently I have lost “the ability to breathe”, since I don’t automatically jump on every single latest bandwagon without evaluating first. WTAF?!
@MustafaCharts BTW: none of these equations like this require ’genius’ intellect (most are actually trivial in nature).
