Applying properties of Exponents in exercise,use the properties of exponents to simplify the expression.See example 1.
evablogger [386]

Answer: a) 15625, b) 0.2, c) 625, d) 0.008.

Step-by-step explanation:

Since we have given that

a) (5^2)(5^3)

As we know that

a^m\times a^n=a^{m+n}

So, it becomes,

5^2\times 5^3=5^{2+3}=5^6=15625

(b) (5^2)(5^{-3})

So, it becomes,

5^2\times 5^{-3}=5^{2-3}=5^{-1}=\dfrac{1}{5}=0.2

(c) (5^2)^2

As we know that

(a^m)^n=a^{mn}

So, it becomes,

5^{2\times 2}=5^4=625

(d) 5^{-3}

a^{-m}=\dfrac{1}{a^m}\\\\5^{-3}=\dfrac{1}{5^3}=\dfrac{1}{125}=0.008

Hence, a) 15625, b) 0.2, c) 625, d) 0.008.

El interior de un tanque que contiene agua, tiene una presión manométrica de 300 kPa. ¿Qué profundidad tiene el tanque de agua?
zmey [24]

Respuesta:

30,6 metros

Explicación paso a paso:

Dado :

Presión = 300 Kpa

Usando la fórmula que relaciona la presión y la profundidad:

Presión = profundidad * aceleración debida a la gravedad * densidad del agua

Densidad del agua = 1000 kg / m³

Presión = 300Kpa = 300 * 10 ^ 3 Pa

300 * 10 ^ 3 Pa = profundidad * 9,8 * 1000

300000 = profundidad * 9800

Profundidad = 300000/9800

Profundidad = 30,612

Profundidad = 30,6 m
