Question

Which is the simplified form of 18 times q to the fourth power times r all over 6 times q cubed times r to the fifth power.? t0mmiere can you help

3 times r to the fourth power all over q.

12 times r to the fourth power all over.

3 times q all over r to the fourth power.

12 times q all over r to the fourth power.

Answer 1

\[\frac{18q^4r}{6q^3r^5} =\frac{18}{6}q^{4-3}r^{1-4}=3qr^{-4}=\frac{3q}{r^4}\]

Answer 2

thank you zzr0ck :)

Answer 3

can you help me with one more Simplify the expression.

x times the square root of the quantity 64 x cubed, plus 2 x times the square root of x, plus 8 times the square root of the quantity 2 x

Answer 4

\[x*\sqrt{64x^3}+2x*\sqrt{x}+8*\sqrt{2x}?\]

Answer 5

yes thats it

Answer 6

\[8*x^2\sqrt{x}+ 2x \sqrt{x}+ 8*\sqrt{2}*\sqrt{x}=\sqrt{x}*(8x^2+2x+8\sqrt{2})\]

Answer 7

it also askes what the leading coefficient of it would be when it is simplified would it be the eight or sqrt of x

Answer 8

i think its 8x^2 am i right?
