1. Here are three numbers:

1–√k, 2+5√k and 2√k.
Given that K is a positive integer, find:

A) The mean of the three numbers
B) the range of the three numbers

Given that y = 1/25 x^4 , express each of the following in the form Kx^n , where K and n are constants.

A) y^-1
B) 5y ^ 1/2

The ^ sign is a representation of the exponent (to the power of.)
M
