# 54: You can transfer a [unparseable or potentially dangerous latex formula] from 12% to [unparseable or potentially dangerous latex formula], and then you have [unparseable or potentially dangerous latex formula], or [unparseable or potentially dangerous latex formula].

#68: Basically, just use the term of the expansion for the coefficient. In [unparseable or potentially dangerous latex formula], the [unparseable or potentially dangerous latex formula] term is [unparseable or potentially dangerous latex formula], so plug in the numbers (yes, with 3 as the y).

#69: When multiplying common numbers with different exponents, you add together the exponents, therefore [unparseable or potentially dangerous latex formula] is [unparseable or potentially dangerous latex formula], or [unparseable or potentially dangerous latex formula].

#70: Memorize [unparseable or potentially dangerous latex formula], and their exponents up to:10[unparseable or potentially dangerous latex formula],6-ish(e), and 5-ish[unparseable or potentially dangerous latex formula], including each to the e,[unparseable or potentially dangerous latex formula].

After that, these questions are just a matter of quick multiplication.

I hope I helped!
