To find the number that, when raised to the third power, equals 7, you would take the cube root of 7. Mathematically, this can be expressed as ( x = \sqrt[3]{7} ). The approximate value of ( \sqrt[3]{7} ) is about 1.913.
To find the values of X and Y you need two independednt linear equations. There are no equations given, only an expression involving a third variable, i
1.75 + 1.75i7i/2 + 2i = 3.5i + 2i = 5.5i
The fourth root of fifteen raised to the third power is 7.622 (rounded).

This is calculated as follows: (2i)2 = 2i x 2i = 4i2 = 4(-1) = -4.
It is 6+2i. But -6-2i will also serve.
