𝑎^3 + 0.008

Answer:

𝑎^3 + 0.008

According to the equation,

𝑎^3 + 𝑏^3 = (𝑎 + 𝑏)(𝑎^2 − 𝑎𝑏 + 𝑏^2)

So we get,

𝑎^3 + 0.008

= 𝑎^3 + 0.2^3

Using the formula

= (𝑎 + 0.2)(𝑎^2 − 0.2𝑎 + 0.2^2)

= (𝑎 + 0.2)(𝑎^2 − 0.2𝑎 + 0.04)

"hi
students welcome to video learning
so here i am archer sharma
which is your leader tutor for the
question to help you solve the question
which is about
cube root so let's get started
the question we have is a cube plus
0.008
now to simplify the question first
we'll write a cube as it is plus second
number
will convert the 0.008 into
a cube of any number now this 0.008
it can be written as
zero point two cube
like zero point two multiplied by zero
point two multiplied by zero point 0.8
sorry 0.2 like 2 by 10 plus 2 by 10
multiplied by 2 by 10 so it's 8 by
1000 that is equal to 0.008
so it's a cube of a 0.02
so it's 0.02 whole cube
0.2 q now here we are going to apply
a formula aq plus bq is equals to
a plus b in bracket a square
minus a b plus b square
now here we'll write a plus 0.2
in the next bracket it's a square
plus a multiplied by 0.2
plus 0.2 whole square
and square bracket close the next step
is a plus 0.2 the
curly square bracket a square plus 0.2
a plus 0.4
so it's 0.04
so this way we simplify the question for
any doubt
you can write in the comment sections so
let's
highlight
for we just applied one
formula this one for any query write in
the comment sections
for never missing another update
