How do i do square roots by the scientific notation divided and multiplied

In scientific notation numbers are written in the form x×10n , where n is an integer and x is in limits [1,10) i.e. 1≤x<10 . (b) if n is odd, mutiply x by 10 and reduce n by 1 to make it even and then take square root of each and multiply them.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
