Question

Simplify. x 0 yz -3


Simplify. x 0 yz -3

Answer 1

`\small \sf \frac{y}{z {}^( 3)}`

Explanation:

x⁰yz-³

• Any non expression raised to power of 0 equals 1.

`\small \sf \: 1yz {}^( - 3)`

• Express with positive exponents using
  `\small \sf \: a {}^( - n) = (1)/(a^n)`

1y +
`\small \sf \frac{1}{ z {}^( 3)}`

`\small \sf \frac{y}{z {}^( 3) }`

Answer 2

y / z^3

Explanation:

x^0 is 1 because anything to the zero power is 1

1 *y z^-3

We know a^-b = 1/a^b

y / z^3
