Need to find the square root
91
Round to the nearest 10 Ex: 57 60 432 430 31 30
92
4.86 x 10
93
if exponent is positive # move decimal to the right if exponent is negative # move decimal to the left 10
94
Change To
95
Question to ask yourself ?? Is the # more than $1.00?? Yes exponent positive No exponent negative
97
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
