Solve negative one fifth times the quantity 3 minus 12 times the quantity one third squared end quantity end quantity.
katrin [286]

The solution to the given equation is -87/45

<h3>Product of expressions</h3>

Given the following expression that represents the word problem as;

-1/5 * 3 - 12(1/3)^2

Using the PEMDAS rule, the parenthesis and exponent will come first to have;

-1/5 * 3 - 12(1/3)^2 = -1/5 * 3 - 12(1/9)

Then multiplication

-1/5 * 3 - 12(1/9) =. -3/5 - 12/9

Find the difference

-1/5 * 3 - 12(1/9) = -27-60/45

-1/5 * 3 - 12(1/9) = -87/45

Hence the solution to the given equation is -87/45
