X = 4 and Y = 9. I did a complicated way of doing it so if u copy it it would look weird
1 + 1 + 1 + 2 = 5
5 x 9 = 45
Therefore, the total number of km is 45.
This should be the answer. Hope this helps! The three next terms are 25, 31, 37.
1080 degrees because it is an octagon
Hello!
The answer are:
- Product of powers.
- Power of a power.
- Negative exponents.
<h2>Why?</h2>
Let's solve it!
It's a math rule that we must solve first what's into a brake or parenthesis, so,
First: Product of powers
According to the exponent's law, we have a product of powers case, so, we need to sum the exponents and keep the base
Exponents: 5 and 3
Base: 7
Applying it we have:
Then,
We have a power of a power case, which involves multiplying the exponents:
Exponents: 3 and -4
Then,
Finally, we can apply the negative exponents, the negative exponent's rules state that negative exponents are the reciprocal of the positive exponents,
So, we will have that:
Have a nice day!
