What is 6 x 100 + 1 x 10 + 2 x 1 + 5 x
+ 2 x
104
?
1000?

6*100 + 1*10 + 2*1 + 5 + 2*104

600 + 10 + 2 + 5 + 208

612 + 213

825

a² + b²= c²

24² + 7² = c²

c= 25

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
