Whats the answer to x^3 y^0 z^-2
Elina [12.6K]

Answer:

\frac{x^3}{z^2}

Step-by-step explanation:

There are no given values, therefore we can't determine a definite answer. However, we are able to simplify the expression.

As we all know that any variable or number to the power of 0 is equal to 1. This means that y^0 = 1.

We also know that a negative power can bring the variable down and make it a fraction. This means that z^-^2=\frac{1}{z^2}

Now that we got these two sorted we are able to write it in a simplified form.

Answer: \frac{x^3}{z^2}

Your monthly living expenses are $1500 on an income of $1,650 per month. Your goal is to have an emergency fund of 4 times your
Aneli [31]
For the answer to the question above, your end goal is to have $6,000 total in 12 months. since you have $2400 already you can subtract that from 6,000 leaving you with $3600 over the course of 12 months. since you already put $150 in a month over the course of 12 months you would have $1800 which is only half of the goal of $3600. in order for you to put in $3600, you would have to put an additional 150 in your savings along with your regular 150 making Letter B the answer.
