Question

5a*2ab​

Answer 1

$5a \times 2ab \\ 10a {}^{1} \times a {}^{1} b \\ 10a {}^{1 + 1}b \\ 10a {}^{2} b$

Answer 2

To simplify the expression 5a*2ab, we can multiply the coefficients (numbers) and combine the variables.

The coefficient of the first term is 5, and the coefficient of the second term is 2. When multiplying these coefficients, we get:

5 * 2 = 10

Now let's consider the variables. In the first term, we have "a" as a variable, and in the second term, we have "ab" as a variable.

When multiplying variables, we add their exponents. In this case, we have "a" raised to the power of 1 (a^1) in the first term and "a" raised to the power of 1 (a^1) and "b" raised to the power of 1 (b^1) in the second term.

Combining the variables, we get:

a^1 * a^1 * b^1 = a^(1+1) * b^1 = a^2 * b

Putting it all together, the simplified expression becomes:

10a^2b
