(2x + 1) + (7x - 10) = 90. [WXY is a right angle]
9x - 9 = 90
9x = 99
x = 11
WXZ = 2x + 1 = 2 x 11 + 1 = 23 degrees

For this case we have to define root properties:

$\sqrt [n] {a ^ n} = a ^ {\frac {n} {n}} = a$

In addition, we know that:

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

On the other hand:

$4 ^ 2 = 16$

Thus, we can rewrite the given expression as:

$\sqrt {4 ^ 2 * a ^ 8 * \frac {1} {b ^ 2}} =\\4 ^ {\frac {2} {2}} * a ^ {\frac {8} {2}} * \frac {1} {b ^ {\frac {2} {2}}} =\\4 * a ^ 4 * \frac {1} {b}$

Find the nth term of this 5 7 9 11 13

NemiM [27]

Firstly, seeing that the sequence is based on odd numbers I would say that this is the formula (which will allow you to know whatever term):

nth term = 2n-1

Hope this helps!
