Question

[12 -: 6 * 5]^(2)- 14 7=N. Find the value of N

Answer 1

[12/30]^2 -147 =

4/25 - 147 = - 146 21/25 = N = 146.84

you seem to be using -: to indicate division, and * for multiplication

PEMDAS is the order of operations, simplify what's in parentheses or brackets first. 6x5=30, then do the division 12/30 = 2/5. Then the exponent to get 4/25, last subtract 147

But your 147 looks like it might be 14 7 which sometimes has showed up for some reason as really meaning 14/7. IF so then 14/7 = 2 and 2/5-2 = (2-10)/5 = -8/5
