To simplify the expression 3a^2 * 4a^5, you can first multiply the coefficients 3 and 4 to get 12. Then, you add the exponents of 'a', which gives you a total exponent of 7. Therefore, the simplified expression is 12a^7.
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
6-3a**2+7+4a-5a+18 3a**2-1a+31
The expression 4a - 5 - a + 2 can be simplified by combining like terms. Combining the terms with 'a', we get 4a - a = 3a. Combining the constants, we get -5 + 2 = -3. Therefore, the simplified expression is 3a - 3.
4a-2=7a-6 4=3a a=4/3
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2

4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2

The expression 4a - 5 - a + 2 can be simplified by combining like terms. Combining the terms with 'a', we get 4a - a = 3a. Combining the constants, we get -5 + 2 = -3. Therefore, the simplified expression is 3a - 3.
4a-2=7a-6 4=3a a=4/3
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
(4a)2 or 16a2
1/2
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.
