View Full Version : simplify x^2/Y3 (square root of x + square root of y^3)
simplify using the laws of exponents
x^2 (square root of x + square root of y^3)
Y^3
I'm not sure where to start this question

Is \ this \ what \ you \ want \ to \ simplify: \ \frac{x^{2}[x^{1/2}+y^{3/2}]}{y^{3}}?
no
X^2 (square root of x + square root of y^3)
y^3

How \ about \ this: \ \frac{\sqrt x^{2}}{\sqrt y^{3}} \ ?
no
x^2
y^3
Is the first part of the expression, it is all multiplied by ( square root of x + square root of y^3)
Is there a square root sign on the computer?

Hey \ Wood, \ x^{1/2} = \sqrt x.
ok so,
x^2 all multiplied by( x^1^/^2 + (y^3)^1^/^2
y^3

See my first answer, there is nothing to simplify except combining terms in the numerator.

If you are using standard MS keyboard then to type square-root sign (?)- type <ALT>251 on the number key-pad with "numlock" key activated.
so the Y^3 that is the denominator in the question is only under X^2 how do I get it to be the denominator for the entire question.

Do you agree with following?
\frac{2}{3}\cdot [2 + 3] \,
=\frac{2}{3}\cdot \frac{[2 + 3]}{1} \,
= \, \frac{2\cdot [2 + 3] }{3\cdot 1}
= \, \frac{2\cdot [2 + 3] }{3}

Those are the same steps.....
so
x^2(x^1^/^2+y^3^/^2)
y^3
2/1*1/2=2/2=1
x + x^2y^3^/^2
Y^3
is this my final answer?

Woody, you haven't been listening!
If you have a/b * c, the b is already the FULL denominator: same as ac / b
AND what are you doing here: x^2y^3^/^2 ?
Do you mean y^(3/2)?
If your teacher is trying to teach how to simplify, he/she should be shot at sunrise
for picking such a ridiculous expression :shock:
