Answer:

13 : 11

Step-by-step explanation:

If the ratio of radii = a : b, then

ratio of areas = a² : b²

Given

ratio of areas = 169 : 121, then

ratio of radii = $\sqrt{169}$ : $\sqrt{121}$ = 13 : 11

Show why the following statement is true:<br> 2^−1/2 = 1/2^1/2

Alik [6]

In order to solve a negative exponent, you have to consider the multiplicative inverse of the base:

$a^{-m}=\dfrac{1}{a^m}=\left(\dfrac{1}{a}\right)^m$

So, if we solve the negative exponent on the left hand side, we have

$2^{-\frac{1}{2}}=\dfrac{1}{2^\frac{1}{2}}=\left(\dfrac{1}{2}\right)^{\frac{1}{2}}$

which is the right hand side.
