Question

Multiply and simplify.
y^3*y^-5*y^-2*y

Answer 1

\[3-5-2+1\] will be your exponent

Answer 2

y^-3

Answer 3

well the options are -
A. y^-4
B. 1/y^4
C. y^-5
D. 1/y^3

Answer 4

1/y^3

Answer 5

or if you prefer:
\[y^3y^{-5}y^{-2}y=\frac{y^3y}{y^5y^2}\]
\[\frac{y^3y}{y^5y^2}= \frac{y^4}{y^7}\implies\frac{\cancel{y^4}}{\cancel{y^4}y^3}\]
\[\frac{1}{y^3} =y^{-3}\]
