Iwill give branliest and 15 points which of the following expressions is correctly written in scientific notation? a.1.4 × 105 b.0.32 × 103 c.5.62 × 210 d.11.2 × 101

A. 1.4 × is written correctly in scientific notation

0.32 ×  needs to be 3.2 ×

5.62 × is just wrong its always × 10

11.2 × needs to be 1.12 ×

There is always 1 number before the decimal and that number is always greater than 0 and the number after × is always 10

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
