The answer is square root of 39. 64-25=39
I believe the Answer is a/22 ( that’s a fraction )
Answer:
To find the cube root of a number is a bit more complicated and in our days is considered impractical, but here is a method explained. Look at the 2nd example scrolling down about 1/3 of the page
If you want to know the concept of square roots and cube roots ?
the square root of a number is that number which when multiplied by itself two times gives us that number
e.g.
√64 = x , so that (x)(x) = 64
and from our multiplication table we know that
(8)(8) = 64 , so that
√64 = 8
the cube root of a number is that number which when multiplied by itself three times gives us that number
e.g.
∛64 = x , so that (x)(x)(x) = 64 , and thus x = 4 because 4x4x4 = 64
so ∛64 = 4
for 9 I wrote Any decimal which terminates is rational
any decimal which has a repeat is rational
any decimal which does not show any repeating decimals and which is never-ending is irrational
Step-by-step explanation:
Answer:
Ok, sabemos que Carlos ha construido un 3/7 de una casa.
Queremos saber cuanto le falta para terminar de construirla.
Entonces podemos realizar el cálculo:
1 casa - lo que Carlos ya construyo = Lo que le falta.
Entonces:
1 casa - 3/7 de una casa = X
Podemos reescribir:
1 casa = 7/7 de una casas
así tenemos:
7/7 de una casa - 3/7 de una casa = X
(7/7 - 3/7) de una casa = X
4/7 de una casa = X
Así podemos concluir que a Carlos le falta construir 4/7 de una casa para acabar.
