What is the value of n?
7.8x10^6=(3x10^4) (2.6x10^n
The value of n is...

n = log()

Step-by-step explanation:

Take the logarithm of both sides of the equation to remove the variable from the exponent.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
