Simplify<br> 21x^6 y^5<br> 14x^2y^9

PIT_PIT [208]

Answer:

$\frac{3x^{4} }{2y^{4} }$

Step-by-step explanation:

Factor out 7 from top and bottom :

$\frac{7(3x^6y^5)}{7(2x^2y^9)}$

Divide top and bottom by 7 :

$\frac{3x^6y^5}{2x^2y^9}$

Simplify :

$\frac{x^6}{x^4}=x^{2}$

Simplify :

$\frac{y^5}{y^9} = y^{-4} = \frac{1}{y^{4} }$

Collect everything together :

$\frac{3x^{4} }{2y^{4} }$

Please tell me correct and

choli [55]

Answer:

$\frac{1}{4}$ or $0.25$ (they're the same)

Step-by-step explanation:

First Part:

$4^{3} = 64$
$8^{2} = 64$
$2 = 2$
Multiply them together: 64 × 64 × 2 = 8192

Second Part:

$2^{7} = 128$
$16^{2} = 256$
Multiply them together: 128 × 256 = 32768

Wrap it all up:

8192 ÷ 32768 = 0.25 = 1/4

I hope this helps!

Answer:

x = 11

Step-by-step explanation:

Given :

AB = x + 5

BC = 2(x - 3)

AB = BC

x + 5 = 2(x - 3)

x + 5 = 2x - 6

5 + 6 = 2x - x

11 = x

x = 11
