Given expression:
13)
15)
Write the expressions in radical form.
Solution:
For an expression with exponents as fraction like
the numerator represents the power it is raised to and the denominator represents the nth root of the expression.
For an expression with exponents as negative fraction like
We take the reciprocal of the term by rule for negative exponents.
So it is written as:
using the above properties we can write the given expressions in radical form.
13)
⇒ [Using rule of negative exponents]
⇒ [writing in radical form]
15)
⇒ [Since 2nd root is given as in radical form]
Answer:
8 dogs

I would appreciate Brainliest but no worries.
14 gal × (26 mi)/gal = 14×26 mi = 364 mi
<span>He can drive 364 miles on one tank of gasoline. </span>
<span>838 mi × (1 tank)/(364 miles) ≅ 2.3 tanks </span>
<span>He needs to stop twice to refill the tank.

A = 3n - 2p
A = 3(7) - 2(-6)
A = 21 - (-12)
A = 21 + 12
A = 33
The answer is 6290 because 17%•37000 is 6290
