= (5a²)³ - 4³
you can apply the cubic factorisation rule
(a³ - b³) = (a - b)(a² - ab + b²)
= [5a² - 4][ (5a²)² - 20a² + 16]
= [5a² - 4][25a⁴ - 20a² +16]
I think this is it.
hope it helps.

Since you're familiar with the place value associated with decimal digits, you know that the 1 in this number, being 4 places to the right of the decimal point, has a place value of 1×10⁻⁴. This means the number can be written as
1.27×10⁻⁴
