The answer depends on the context.
· The standard form of a number looks like a*10b where 1≤a<10 and b is an integer.
· In analytical geometry the standard form of an equation of a straight line in n-dimensional space is
a1x1 + a2x2 + ... + anxn + c = 0
· In 2-dimensional space, that simplifies to
ax + by + c = 0
· Still with analytial geometry the standard form of an equation of a hypersphere in n-dimensional space is
(x1- a1)2 + (x2- a2)2 + ... + (xn- an)2 = r2 where (a1,a2,... an) is the centre, the xi are as before, and r is the radius.
· In 2-dimensional space, that simplifies to
(x- a)2 + (y- b)2 = r2 where the centre is (a,b)
There are standard forms for all sorts of shapes. And there are standard forms in other branches of mathematics.

Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form.
