Answer:

x = 2.564 ( to 3 dec. places )

Step-by-step explanation:

Using the rule of logarithms

log $x^{n}$ ⇔ n logx

Given

$5^{x}$ = 62 ( take the ln of both sides )

ln $5^{x}$ = ln 62, that is

x ln5 = ln 62 ( divide both sides by ln 5 )

x = $\frac{ln62}{ln5}$ ≈ 2.564

Here, Pages in books = Number of books * number of pages in one book

So, Pages of picture book = 10 * 25 = 250
& Pages of chapter book = 120 * 5 = 600

So, Number of Total pages = 250 + 600 = 850

So, Option (D) is your answer! Hope this helps!!

Hello!

$\large\boxed{x^{4}}$

Recall that:

$\sqrt[z]{x^{y} }$ is equal to $x^{\frac{y}{z} }$ . Therefore:

$\sqrt[3]{x^{2} } = x^{\frac{2}{3} }$

There is also an exponent of '6' outside. According to exponential properties, when an exponent is within an exponent, you multiply them together. Therefore:

$(x^{\frac{2}{3} })^{6} = x^{\frac{2}{3}* 6 } = x^{\frac{12}{3} } = x^{4}$
