First multiply 5 and 2 together

5 x 2 = 10

The numerator is 3^10

Now look at the denominator. It is 3^-2. In the even of seeing a negative number inside the exponent, flip the number from denominator to numerator, or vice versa.

1/3^-2 = 3^2

Add:

3^10 + 3^2 = 3^12

3^12, or D is your answer

hope this helps

What is the total surface area of this square pyramid?

slamgirl [31]

Answer:

The total surface area of this square pyramid is $297\ mm^{2}$

Step-by-step explanation:

we know that

The surface area of a square pyramid is equal to

$SA=b^{2} +4[\frac{1}{2}(b)(h)]$

we have

$b=9\ mm$ ----> the length side of the square base

$h=12\ mm$ ----> the height of the triangular faces

substitute the values

$SA=9^{2} +4[\frac{1}{2}(9)(12)]=297\ mm^{2}$
