Question

For 20 Points. 3 Qs.
I also gave you guys a help sheet. PLEASE HELP.

Answer 1

wat is help sheet, didn't help,

instructions unclear, got my calculator stuck in the ceiling fan

remember some simple exponential laws

`( x^(n) )(x^(m))=x^(n+m)` and

`(x^(n))/(x^(m)) =x^( n-m )`

`x^(-m)= (1)/(x^(m))`

first one

`(2^(-6))(2^(3))=2^(-6+3)=2^(-3)= (1)/(2^(3)) = (1)/(8)`

2nd one

`(7^(5))/(7^(3)) =7^( 5-3 ) = 7^(2) = 49`

third one

`(3^(-4))(3^(2))=3^(-4+2)=3^(-2)= (1)/(3^(2)) = (1)/(9)`


dunno wat to do with 'help sheet'
