Basically u evaluate it into (3⁶y⁵)² then use the properties of exponents to simplify to (729y⁵)² and then ur answer is 729²y¹⁰ or in other words, 3¹²•y¹⁰ so ur answer is B.
Step-by-step explanation:
x^3 is a perfect cube, 8 is a perfect cube, so we use difference of cubes.

Cube root of x^3 is x.
Cube root of 8 is 2
So
a=x
b= 2.

Set these equations equal to zero



If we do the discriminant, we get a negative answer so we would have two imaginary solutions,
Thus the only real root is 2.
If you want imaginary solutions, apply the quadratic formula.

Answer:
To find the answer we only need to know,
Total no.of girls and Total no.of right handed girls.
So,
Total no.of right handed girls = 7/8
Total no.of girls = 8/8 (as given in question)
Total no.of left handed girls is,
(Fraction of total no.of girls) - (Fraction of total no.of left handed girls)
= 8/8 - 7/8
= 1/8
∴ 1/8 of the girls in the school are left handed.
