Can I ask how you got 60?
The answer is 244,140,625
When multiplying/dividing, exponents are added/subtracted respectively.
5^12
5x^2 + 6x - 2
To simplify the expression (5^3) * (5^9), we can use the rule of exponents, which states that when you multiply two powers with the same base, you can add their exponents.
The expression (5^3) * (5^9) can be rewritten as 5^(3+9), which simplifies to 5^12.
Now we can evaluate 5^12:
5^12 = 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5
By multiplying all the 5's together, we find that 5^12 equals 244,140,625.
Therefore, the answer to (5^3) * (5^9) is 244,140,625, not 60.
Now let's work on the expression (3x-2) and (5x^2+3x):
To combine these two expressions, we need to distribute the terms of the first expression (3x-2) onto the terms of the second expression (5x^2+3x). This means multiplying each term in the first expression by each term in the second expression.
Using the distributive property, we can simplify the expression as follows:
(3x-2)(5x^2+3x) = 3x * 5x^2 + 3x * 3x - 2 * 5x^2 - 2 * 3x
Simplifying further:
15x^3 + 9x^2 - 10x^2 - 6x = 15x^3 - x^2 - 6x
Therefore, the simplified expression for (3x-2)(5x^2+3x) is 15x^3 - x^2 - 6x.
