Question

Use the rules of exponents to evaluate or simplify. Write without negative exponents.

Answer 1

Answer:

• 2

Step-by-step explanation:

• $(\frac{1}{4})^{-1/2}$ =
• $(\frac{1}{\frac{1}{4} })^{1/2}$ =
• $4^{1/2}$ =
• $2^{2*1/2}$ =
• $2^{1}$ =
• 2

Properties used

• $a^{-b} = (\frac{1}{a} )^b$
• $(a^{b} )^c = a^{bc}$

Answer 2

• a^{-m}=(1/a)^m
• (a^m)^n=a^mn

So

• (1/4)^{-1/2}
• 4^{1/2}
• √4
• √2²
• 2
