-16t^2+400=0

16t^2=400

take square root on both sides.

$\sqrt{16t^2} =\sqrt{400}$

4t=20

t=20/4

t=5

(3a^4b)(5ab^2)-(a^5b^2)(9b)

Sliva [168]

Answer:

The expanded value of the given expression is

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=6a^5b^3$

Step-by-step explanation:

Given expression is

$(3a^4b)(5ab^2)-(a^5b^2)(9b)$

To find the value of the given expression:

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=15a^5b^3-9a^5b^3$

(By multiplying the products and doing algebraci subtracion of the above expression)

Now taking the common terms in the above equation we get

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=3a^5b^3(5-3)$

$=3a^5b^3(2)$

$=6a^5b^3$

Therefore the expanded value of the given expression is

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=6a^5b^3$
