Answer:
Step-by-step explanation:
Use laws of exponents to simplify the right set of parentheses.
Now use the law of exponents for a product of powers with the same base.
Finally, use the definition of a negative exponent.
Answer:
Do 220 - 8 to find the remaining amount of numbers left to 220, which is 212. Since 212 isn't divisible by 3, which is the increase in the sequence, 220 isn't part of the sequence below.

Answer:
270 & 30
Step-by-step explanation:
let the number is n,
the equation :
n× 1/9 n= 27(n +1/9 n)
1/9 n² = 27n + 3n
1/9 n² = 30n
1/9n²- 30n = 0
n(1/9n -30)= 0
n = 0 or
1/9n = 30 => n = 30×9 = 270
270 is a number,
the other : 270/9 = 30
Answer:
No
Step-by-step explanation:
Pythagorean Theorem
60 x 60 = 3600
82 x 82 = 6724
6724 + 3600 = 10324, not 10000 (100 squared)
So it isn't a right triangle
