Rewrite the expression in z to the n power. The expression I was given is: 1 over z to the negative 1 half power.
12345 [234]

Answer:

The equivalent expression is;

\frac{1}{z^{-\frac{1}{2}}}=z^{\frac{1}{2}}

Step-by-step explanation:

The given expression is:


\frac{1}{z^{-\frac{1}{2} }}

Recall that:

\frac{1}{a^{-m}}=a^m


In our case, a=z and  m=\frac{1}{2}.


We use this property of exponent to obtain;

\frac{1}{z^{-\frac{1}{2}}}=z^{\frac{1}{2}}

The mean of three numbers is 70. if two of the numbers are 55 and 65 what is the third number
Margarita [4]
90
55+65=120
there are 3 numbers and when you divide them it makes 70.
70 x 3 = 210
210 - 120 = 90
55 + 65 + 90 = 210
210 / 3 = 70
