Find the side

Need to find the square root

Round to the nearest 10

Ex: 57 60 432 430 31 30

4.86 x 10

Question to ask yourself ??

Is the # more than $1.00??

Yes exponent positive

No exponent negative

When expression is given --substitute n with 1 , 2 , 3 , 4

EX: 3n + 4 3(1) + 4 = 7 3(2) + 4 = 10 3(3) + 4 = 13 3(4) + 4 = 16
