3^-6 times 3^4 ( the ^is exponents)

0.1 repeating, or 1/9

Step-by-step explanation:

To solve, you have to first leave the 3, then add up the exponents,

4 - 6 = -2.

Then -2 becomes the exponent, so 3^-2.

When simplified to a number, it is

0.1 repeating, or 1/9.

Hope this helps!!

Let me know if I'm wrong or you need help on a different problem!!

33.5 unit²

it's a mixture of triangle and square.

draw a imaginary straight line across the figure from that line which has length of 3 units and now you can see the triangle and the square. Use the formula to find area of triangle and area of square and the sum of their area will be the area of this whole figure i.e 35.5 unit²
