I need help with two of these questions, I drew them out below. All it says is to simply, I reckon they aren't hard problems.

I appreciate anyone who helps, this is on a quiz I took today & was wondering the answers.

 

What is it your teacher wants you to do with these?

What is it your teacher wants you to do with these?

 

Just simplify them.

Assuming that 3 isn't a third root, it would be:

 

[ (3)(10)(x^4)(y^5) ] / [ (-2)(5)(a^2)(b^3)(c^7)(sqrt2ac) ]

 

= -3(x^4)(y^5) / (a^2)(b^3)(c^7)(sprt2ac)

 

At this point, depending on what your teacher requires, you make need to simplify the square root in the denominator. You would do this by multiplying your whole fraction by (sqrt2ac) / (sqrt2ac)

 

 

Your final answer would be:

 

(-3)(x^4)(y^5)(sqrt2ac) / (2)(a^3)(b^3)(c^8)

1) 30(x^4)(y^8)

 

2) not too sure about the second one - i could answer it, but in absolute values

wait are they 2 separate q's or just one q?

Two separate questions.

There is no answer
