To simplify (2t–3)3(0.4r)2 %0D%0Awe can simplify each expression separately and then multiply them together.
First, let's simplify (2t–3)3:
(2t–3)3 = 2^3 * t^3 * (-3)^3
= 8t^3 * (-27)
= -216t^3
Next, let's simplify (0.4r)2:
(0.4r)2 = 0.4^2 * r^2
= 0.16r^2
Now we can multiply these two simplified expressions together:
-216t^3 * 0.16r^2 = -34.56t^3r^2
Therefore, the simplified expression is -34.56t^3r^2.
