Simplify: 5g (3g + 7g² - 9)

A. 50g⁴ - 45g

B. 15g2 +35g – 45g

C. 8² + 12g³ – 4g

D. 8g + 7g²- 9

E. 5g⁴

You need to use these two rules of exponents:
To raise a product to a power, raise each factor to the power.
To raise a power to a power, multiply the powers.

The product inside the parentheses is being raised to the power 1/2.
Raise each factor to the power 1/2.





Now multiply the exponents.



Finally, use the definition of a rational exponent to change the exponent of x into a root.
