Anything (except zero) to the power of zero is 1. If written as 7a0, this is operated as 7 x (a0) = 7 x 1 = 7. If written as (7a)0, it is simply 1 by the first statement.

How do you do 7a plus 10 equals 2a?
7a+10=2a 7a+10-2a=0 5a+10=0 5a=-10 a=-2
3a 4b equals 7a 4b?
Clearly, there are some signs missing. So let's try the four possibilities for the second terms: 1. + and + 3a + 4b = 7a + 4b Subtract 4b from each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 2. + and - 3a + 4b = 7a - 4b Subtract 4b from each side: 3a = 7a - 8b Subtract 7a from each side: -4a = -8b or 4a = 8b Answer: a = 2b 3. - and - 3a - 4b = 7a - 4b Add 4b to each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 4. - and + 3a - 4b = 7a + 4b Add 4b to each side: 3a = 7a + 8b Subtract 7a from each side: -4a = 8b or 4a = -8b Answer: a = -2b Can't do better than that with the information available.
What is -7a plus 3a?
-7a + 3a = -4a
What is 3a 7a simplified?
It is: 3a+7a = 10a simplified
How do you solve 7a-b equals 15a and solve for a?
-8
How do you simplify a2 plus 7a-8a2 equals 6a7?
a2 + 7a - 8a2 = 6a7 ∴ a2 + 7a - 8a2- 6a7 = 0 ∴ a + 7 - 8a - 6a6 = 0 ∴ 7 - 7a - 6a6 = 0 ∴ 6a6 + 7a - 7 = 0

Evaluate 3 a plus 4 a 6?
3a + 4a +/- 6; take the 3a & 4a and combine them; 7a +/- 6 would be your answer as 6 cannot combine with 7a due to the variable. If 7a +/- 6 = 0, then subtract/add (respectively) the 6 depending on the operation. Therefore 7a + 6 = 0 turns to 7a = -6. Divide the 7 with the -6 to get the a alone; a = -6/7 or -0.8. Cannot be simplified.
If a and b has a LCM of 40 what is 7a power of 3 and 7b the power of two LCM?

Solve 121a equals 49acubed by facturing?
121a=493 0=49a3 - 121a Subtract 121a over 0=a(49a2 - 121) factor out an a, leaving Difference of Squares 0=a(7a-11)(7a+11) a=o a=11/7 a=-11/7
Solve the equation 9a-a equals 19 plus 7a?
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
