simple math! FULL RATING THOU!?

[-59 x (-3) + 21]/(√512)
= [177 + 21]/[√(2^8 x 2)]
= 198/[√(2^8 x 2)]
= 198/[2^4√2]
= 198/[16√2]
= 99/[8√2]
= (99 x 8√2)/(8√2 x 8√2)
= (792√2)/128
= (99√2)/16

Question is difficult to tread.
Will GUESS at :-

(-59) (-3) + 21
----------------------
√ 512

127 + 21
------------
16√2

148
--------
16√2

8
---
√2

4√2

I don't know why do you have to ask this,Anyway here's the solution

According to BODMAS
root of 512 = 22.627
21/22.627 = 0.928
-59 X -3+0.928 = 177+0.928 = 177.928

((-59)*(-3)+21)/(512)^0.5 = 8.75 to 2dp

if its (-59*-3)+(21/(512)^0.5) then its 177.93 to 2dp

sorry not sure what the question is but hope this helps

(177X*(sq root of 2)+21*(sq root of 2))/2

8.7504

yes

Yes, it is simple, so work it out for yourself!

God! People are so lazy!
