how is the following simplified
3x to the third power plus 5x to the fifth power
x^3(3 + 5 x^2)
To simplify the expression 3x^3 + 5x^5, we can combine the like terms with the same exponent. In this case, both terms have an x raised to a power.
Step 1: Write the expression using descending order of exponents.
5x^5 + 3x^3
Step 2: Group the terms with the same exponent.
(5x^5) + (3x^3)
And that's the simplified form of the expression 3x^3 + 5x^5.
