Question

e) The square of 4/5 is
​

Answer 1

Answer:

So technically, we can write the square root of 4/5 as...

sqrt(4) / sqrt(5)

And then simplify it as thus...

2 / sqrt(5)

Now we need to move the square root to the numerator. We can do it like this.

( 2 / sqrt (5) ) * ( sqrt(5) / sqrt (5) )

= 2 * sqrt(5) / 5

If you were asked for the exact answer, then leave it as is. If asked for a rounded answer, then find the square root of 5 using a calculator, and go on from there.

Answer 2

Answer:

16/25

Step-by-step explanation:

${(\frac{4}{5} ) }^{2}$

$\frac{ {4}^{2} }{ {5}^{2} }$

$\frac{16}{25}$
