Scientific notation says, "leave only one guy to the left of the decimal point", so... 25.8 needs to turn to 2.58 then... multiplied by some power of 10, we just need to move the dot over one spot, so 10 at the 1 power, $\bf 2.58\times 10^1\implies 2.58\times 10$

Answer ---> 2.58*10^1

So, when you write 10^n, you have to move the comma n times.

So you move the comma 1 time from 2.58 (moved the comma 1 time on the left) to the right and get 25.8

Blizzard [7]

Answer:

La hija mayor recibirá 17.5 perlas, la hija del medio recibirá 11.66 perlas, y la hija menor recibirá 3.88 perlas.

Step-by-step explanation:

Dado que Marcella le pide a Dora que la ayude a dividir 35 perlas entre sus tres hijas, y quiere darle la mitad a la hija mayor, la tercera parte a la del medio y la novena a la menor y, además, Marcella quiere darle una perla a Dora como recompensa, para determinar cuántas perlas recibirá cada hija se debe realizar el siguiente cálculo:

35 / 2 = Mayor = 17.5 perlas

35 / 3 = Medio = 11.66 perlas

35 / 9 = Menor = 3.88 perlas

Así, la hija mayor recibirá 17.5 perlas, la hija del medio recibirá 11.66 perlas, y la hija menor recibirá 3.88 perlas.
