The equivalent expression for 3a * 4b is 12ab. This is because when you multiply terms with the same base, you add their exponents. In this case, a is raised to the power of 1 and b is raised to the power of 1, so when you multiply them together, you get a^1 * b^1 = ab. Finally, multiplying 3 and 4 gives you 12, so the equivalent expression is 12ab.
36 -20 = 16
3a + 4b - 5 - 1a + 7b + 3 - 1b 2a + 10b - 5 + 3 2a + 10b - 2
4b - 3
a + b = 21 so a = 21 - b; 3a = 4b so 3(21 - b) = 4b ie 63 - 3b = 4b so 7b = 63 making b = 9 and a = 12
To solve the expression (7a + 4b - 1), you typically need to know the values of (a) and (b). Once you have those values, you can substitute them into the expression and perform the arithmetic to find the result. If no specific values are given for (a) and (b), the expression remains in its simplified form.
6a²b - 12ab²
4b-b
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
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.
1 x1 =1 2x2=4 and it goes on and on bye see you later
Ans. 2a-5b
The given expression can be simplified to: 3b-a
36 -20 = 16
3a + 4b - 5 - 1a + 7b + 3 - 1b 2a + 10b - 5 + 3 2a + 10b - 2
15
To simplify the expression 3a x 4b, you multiply the coefficients (numbers) together, which gives you 3 x 4 = 12. Then, you multiply the variables together, which gives you a x b = ab. Therefore, the simplified expression is 12ab.
This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)
