Answer:
7.2 *10⁻⁵
Step-by-step explanation:
Given the diameter of the hair expressed as 0.000072, we are to express it in scientific notation.
The standard form of scientific notation is expressed as;
A * 10ⁿ
A is a value from 1 to 9
n is any integer.
Rewriting 0.000072 in this form, we will need to shift the decimal point to the front 5 times to have;
0.000072 = 7.2 *10⁻⁵ where;
A = 7.2 and n = -5
Note that the power is a negative value since the value is less than 1.
Multiply both sides by 8
B = 27 x 8
B = 216
Answer:
The constant in this expression is 5 (btw, a constant is a number on its own)
I miss compatible numbers round 2593 too 2,600 then round 6 to ten and your answer is 260 hope this helps:D
5 times 5 times 5 times 5 is 20
So just count by 5
Hope this help
