Maya is making dream catchers with her family. Each dream catcher takes 1.53 feet of string. She has 6 people in her family. How much string does Maya need total?

1.53*6=9.18

You know where to put the decimal because you count how many places in the decimal is for the two numbers being multiplied (the only decimal in the two numbers being multiplied is in the number 1.53 and that’s is two places in) and then go that many places in on the product (918 two places in from then right would be 9.18)

Simplify the expression. x4y−4z−2x2y−2z4 y2x2z6 the fraction with numerator y squared and denominator x squared z to the 6th pow

Kaylis [27]

Given:

Consider the given expression is:

$\dfrac{x^4y^{-4}z^{-2}}{x^2y^{-2}z^4}$

To find:

The simplified form of the given expression.

Solution:

We have,

$\dfrac{x^4y^{-4}z^{-2}}{x^2y^{-2}z^4}$

By using the quotient property of exponents, we get

$=x^{4-2}y^{-4-(-2)}z^{-2-4}$ $\left[\because \dfrac{a^m}{a^n}=a^{m-n}\right]$

$=x^{2}y^{-4+2}z^{-6}$

$=x^{2}y^{-2}z^{-6}$

By using negative exponent property, we get

$=\dfrac{x^{2}}{y^{2}z^{6}}$ $\left[\because a^{-n}=\dfrac{1}{a^n}\right]$

The simplified form of the given expression is $\dfrac{x^{2}}{y^{2}z^{6}}$ .

Therefore, the correct option is B.
