to answer on cube root we need to use the prime factorisation.
which means using only prime number and dividing the number by suitable prime number.
after find prime factorisation we know that cube root is 3th power of number.
so if we have same three number we need to take it as one because it is a cube root .

Answer
The exact solution of x is 2.65 for the given equation 3x² + 7 = 28 .
Step-by-step explanation:
The equation given in the question is as follows.
3x² + 7 = 28
Now simplify the above eqaution
3x² = 28 - 7
3x² = 21
x² = 7
x = 2.65
Therefore the solution for x is 2.65 for the given equation 3x² + 7 = 28 .
