Question

Multiple -2/3a square b by 6/5 a cube b square and verify your answer for a=2 and b=3​

Answer 1

Answer:

691.2

Step-by-step explanation:

(-2/3a²b)*(6/5a³b²) = -4/5a⁵b³

So, we know that a = 2, b = 3.

-2/3*2*2*3 = -8.

6/5*2*2*2*3*3 = 432/5.

-8 * 432/5 = -691.2.

Now, substitute a=2 , b = 3 in-4/5a⁵b³

-4/5*2*2*2*2*2*3*3*3 = -4/5*32*27 = 3456/5 = 691.2
