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.

Oh, dude, that's just 3a^2 * 4b^2. It's like when you have 3 apples and 4 bananas, and you just multiply the number of each type together. So, in math terms, you just multiply the coefficients (3 * 4) and the variables (a * a * b * b) to get 12a^2b^2. Easy peasy!
Oh honey, you've got yourself a real math problem there. The equivalent expression for 3a a 4b b is 3a^2 + 4b^2. It's as simple as that, no need to overcomplicate things, darling.
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
p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
