Show the work
Find the power of 10
n = ⌊log10|x|⌋
⌊log10 0.000452⌋ = −4
Divide by 10 to the power of n for the number in front
a = x ÷ 10 to the power of n
0.000452 ÷ 10 to the power of −4 = 4.52
Write it as a × 10 to the power of n, with 1 ≤ |a| < 10
x = a × 10 to the power of n
4.52 × 10⁻⁴
How it works
a × 10ⁿ with 1 ≤ |a| < 10 · engineering notation uses n divisible by 3
