How do I solve this question?

olya-2409 [2.1K]

Hello,

we can simplify as below

$\dfrac{(2p^3q^4)^4}{(-3q^5)^2}*\dfrac{9}{(4p^2q)^2}=\dfrac{2^4p^{12}q^{16}3^2}{3^2q^{10}4^2p^4q^2}=p^{12-4}q^{16-10-2}=p^{8}q^{4}=p^{a+b}q^{b-a}$

So it means that

8 = a+b

4 = b-a

8+4 = a+b+b-a=2b

2b = 12

b = 6

and a = 6 - 4 = 2

hope this helps

A snow globe with a radius of 2 cm. Find the volume of the globe.

sp2606 [1]

The approximate volume is 33.5103217
The exact volume is 32/3cm
so the answers would be 32/3 or 33.49

What is the sum of 3/4 and 18/19 ??

m_a_m_a [10]

The word "sum" means that we have to add.

3/4 + 18/19 (least common denominator= 76)
= 57/76+ 72/76
= 129/76
= 1 53/76.

The sum of 3/4 and 18/19 is 1 53/76~

One solution, infinite solution, or no solution for 9x+8y=15 and 9x+8y=30

stira [4]

Best way to solve would be using Elimination Method. Here's how to solve.
9x + 8y = 15
9x + 8y = 30
To cancel out a variable multiply one equation with -1.
9x + 8y = 15
-1(9x + 8y = 30)
Distribute.
9x + 8y = 15
-9x - 8y = -30
Add both equations together.
0 = -15
So no solution would be your answer. I hope this helps love! :)
