Q. Rewrite the expression in the form yn.y41y45=
Apply quotient rule for exponents: Apply the quotient rule for exponents which states that when dividing like bases, you subtract the exponents.So, (y45)/(y41)=y(45−41)
Subtract exponents to simplify: Subtract the exponents (45)−(41) to simplify the expression.y(45−41)=y44
Simplify exponent: Simplify the exponent 44 which is equal to 1. y44=y1
Recognize power of 1: Recognize that any number to the power of 1 is the number itself. y1=y
