Question

I need Help and I need it FAST!

Answer 1

`\huge a)\frac{1}{ {3}^(9). {6}^(18) }`

Explanation:

to understand this

you need to know about:

• law of exponent
• PEMDAS

tips and formulas:

• 
  `{x}^( - y) < = > \frac{1}{ {x}^(y) }`
• 
  `( {x} ^(z) )^(y) < = > {x}^(y * z)`

let's solve:

`( {3}^(3) . {6}^(6) {)}^( - 3)`

`\frac{1}{( {3}^(3). {6}^(6) {)}^(3) }`

`\frac{1}{ {3}^(3 * 3). {6}^(6 * 3) }`

`\frac{1}{ {3}^(9). {6}^(18) }`
