Step-by-step explanation:

Hey~There!

________________________

→ Formula:

  • D=rt.

→ Write out an equation:

  • 100=12.5x.
  • X= The time it took him to reach the surface.

→ Solve by dividing \bold1\bold2.\bold5 on each side:

  • 12.5 ÷ 12.5 = Cancels~Out.
  • 100 ÷ 12.5=8.

________________________

So based on the work above we can conclude it took the diver:

  • 8~minutes to reach the surface.

Rewrite the expression with rational exponents as a radical expression by extending the properties of integer exponents.
ra1l [238]

The expression will be written as \rm \sqrt[8]{2^5}., the correct option is A.

<h3>What are Exponents?</h3>

Exponents are the base raised to a power, It is written in the superscript of a number.

The expression given in the statement can be written as

\rm \dfrac{ 2^{7/8}}{2^{1/4}}

By the Exponent rule,

\rm \dfrac{a^m}{a^n} = a^{m-n}

So the expression can be written as

<h3>=\rm { 2^{7/8-1/4}</h3>

=\rm 2^{5/8}

=\rm \sqrt[8]{2^5}

Therefore, in radical form, the expression will be written as \rm \sqrt[8]{2^5}., the correct option is A.

The complete question is

Rewrite the rational exponent as a radical by extending the properties of integer exponents.

2 to the 7 over 8 power, all over 2 to the 1 over 4 power

the eighth root of 2 to the fifth power

the fifth root of 2 to the eighth power

the square root of 2 to the 5 over 8 power

the fourth root of 2 to the sixth power
