Question

V-125 - 5 X 32


`3 √( - 125) - 5 * {3}^(2)`
Simplify the following and show all your workings ​

Answer 1

Because of the order of operations, we start the equation backwards because exponents are what we prioritize here.

`3^2 = 9\\\\9 * 5 = 45\\\\√(-125) = -11.1803399\\\\45 - -11.1803399 = 56.1803399\\\\56.1803399 * 3 = \boxed{168.54}` Result rounded to 2 DP
