## Kidthatbro8 one year ago Choose the correct simplification of the expression the quantity 4x over y all to the second power.

1. Kidthatbro8

4 times x to the second power all over y to the second power 8 times x to the second power all over y to the second power 16 times x to the second power all over y to the second power 16 times x to the second power all over y

3. welshfella

4*4 = 16 x*x = ? y*y = ?

4. Michele_Laino

hint: $\Large x \cdot x = {x^{1 + 1}} = {x^2}$

5. Kidthatbro8

so y*y = y^2?

6. Michele_Laino

yes!

7. Michele_Laino

so, what is the right option?

8. Kidthatbro8

A?

9. welshfella

no it cant be A because 4*4 = 16 ( see above) the first part is 16x^2
