I came across the following question. How would I simplify this?

$$(90^{1800} + 30^{800})^2$$?

I'm assuming I would use the algebraic form $$(x + y)^2$$

Let me know if I'm on the right track:

$$(90^{1800})^2 + 2(90^{1800} + 30^{800}) + (30^{800})^2$$

$$(3^{3600}* 30^{3600}) + 2(3^{1800}*30^{1800} + 30^{800}) + (30^{1600})$$

After this i'm lost.... any help would be appreciated.

Do you have any answer options for this question as those could help reach the eventual solution quicker.

You should post the whole question rather than post this complex problem.
