Evaluate the expression 6 squared parentheses 2/5 + 5 parentheses -3

To start off you do what’s in parentheses

2/5 + 5 = 5 2/5 or 5.4 as a decimal

Then the exponent 6^2 which is 36

So far you have 36 (5.4) - 3

Now you multiply 36 by 5.4 which is 194.4

So now you have 194.4 - 3 which equals 191.4 which is you answer.

Hope this helped!

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)
