Answer:
I’ll tell you how to solve these so you can do it yourself easily. If you still don’t understand, tell me and I’ll help out more :)
The exponent—small number in the top corner of another number—means the number of times you multiply the number by itself.
Example:
3²
I have to multiply 3 by 3 twice, therefore I do 3x3 and get 9. 3² = 9!
The · is a multiplication sign and the parenthesis indicate you multiply as well.
I’ll do 4a for you:
I see the exponent is 2, so I have to write:
2/3 · 2/3
I solve that by multiplying the numerators (2x2) and the denominators (3x3).
2/3 · 2/3 = 4/9.
The answer is 4/9.
Answer:
73, 74, 75
Step-by-step explanation:
So the sum of three consecutive integers is 222.
Let's let the first integer be n.
Then the second integer <em>must</em> be (n+1).
And the third integer must be (n+2).
They total 222, thus:
Combine like terms:
Subtract 3 from both sides:
Divide both sides by 3:
So, the first integer is 73.
So our sequence is 73, 74, and 75.
And we're done!
