Question 280267
When we write y^3  it means y * Y * Y  ( y multiplied 3 times)

y^2 means y* y ( y multiplied 2 times)

Suppose you multiply y^3 by y^2

Then it will be y*y*y* y*y   = y^5

But you have multiplied y^2*y^3

You will notice thaat the exponents are added

y^(2+3) = y^5


x^4* x^6 = x^(4+6) = x^10


Similary in division the exponent of denominator is dubtracted from the exponent of the numerator.

x^6  /  x^2   =  x^(6-2) = x^4

a^8 / a^5  = a^(8-5)  = a^3
