Question

Can anyone explain how to work this equations pls?
​

Answer 1

Answer:

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

Step-by-step explanation:

This question is asking you to simplify using the law of indices:

Just to write out the question in fraction form:

$\frac{12y^{7} }{4y^{9} }$

Cancel out the 4:

$\frac{3y^{7} }{y^{9} }$

Cancel out y^7:

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

Hope this helped and brainliest please

Answer 2

Answer:

3/y^2

Step-by-step explanation:

1. Rewrite the division as a fraction.

= 12y^7/4y^9

2. Cancel the common factor of 12 and 4

= 4(3y^7)/4y^9

= 3y^7/y^9

3. Cancel the common factor of y^7 and y^9

= y^7 ⋅ 3/y^9

= 3/y^2
