what

Midnight97:

jayfafr:

first

jayfafr:

distribute the exponent of 3 to each term inside the parentheses

jayfafr:

(2ab)^3=2^3 x (a)^3 x (b)^3=8a^3b^3

jayfafr:

multiply this by a^2b

jayfafr:

not the 2 part in that equation

jayfafr:

but you get

jayfafr:

8a^5b^4

jayfafr:

So, the expression equivalent to (2ab)^3)xa^2b) is 8a^5b^4

If you want too

jayfafr:

when you have 3.652 x 10^-4 this means that you muptly 3.652 by 10 raised to the power of − 4 −4, which effectively moves the decimal point four places to the left.

jayfafr:

So, when converting to standard notation, you get

jayfafr:

0.0003652

jayfafr:

not 36,520

Midnight97:

Alright
