Answer:
Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a + sign or J sign. In , the terms are: 5x, 3y, and 8.
Step-by-step explanation:
Answer:
x= <em>i</em>√30
Step-by-step explanation:
<u>I'm going to go into this under the assumption that you've covered imaginary numbers based on the </u><u>question.</u><u> If I'm wrong then sorry about that.</u>
Okay, so first you want to subtract 30 from both sides
x^2=-30
Then you take the square root of each side.
√(x^2)=√-30
x=√-30
Since it's impossible to square a number to get a negative number, you'll end up with an imaginary number. You have to rewrite x=√-30 to get rid of the negative sign under the radical. Rewriting this will also indicate that it's an imaginary number.
<u>Final</u><u> </u><u>answer</u><u>:</u><u> </u><u>x</u><u> </u><u>=</u><u> </u><u>i√30</u>
Let S3={I, 1, 2, 3, 4, 5}
Then S3 is an non-Abelian group under composition because ab DNE ba
yet A3 is a normal subgroup of S3 which is commutative and contains permutations of even order
you can also take mappings of this group G
onto G'
may be an isomorphism perhaps
