62

Step-by-step explanation:

PEMDAS BEDMAS

16÷8 = 2

2÷2 = 1

1 * 2 = 2

64 - 2 = 62 = 62

62

Step-by-step explanation:

This seems like an overly complex problem, but if we take it step by step, then it becomes much simpler.

Remember the order of operations. That means that we do the work in the parenthesis first. 4^2/8, or 16/8, or 2.

Then the equation is 8^2, or 64, - 2/2*2, or 64 - 2/2 * 2

2/2 = 1, and 1 * 2 = 2

64 - 2 = 62

Hope that this helps!

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)
