Answer:
where is video.Step-by-step explanation:
It looks like they're multiplied, then you can simply add the exponents,
b⁸ * b⁴ = b⁸⁺⁴ = b¹²
remember, b⁸=b*b*b*b*b*b*b*b and b⁴=b*b*b*b
so b⁸ * b⁴ = b*b*b*b*b*b*b*b * b*b*b*b = b¹²
Answer:
![2\sqrt{34}](https://tex.z-dn.net/?f=2%5Csqrt%7B34%7D)
Step-by-step explanation:
We can add a line to create a triangle and a rectangle. The triangle will have side lengths 10 and 6. Furthermore, it will be a right triangle, meaning we can apply the Pythagorean Theorem to find x, the hypotenuse.
![6^2 + 10^2 = x^2\\x = \sqrt{6^2 + 10^2}\\ = \sqrt{136} \\= 2\sqrt34}](https://tex.z-dn.net/?f=6%5E2%20%2B%2010%5E2%20%3D%20x%5E2%5C%5Cx%20%3D%20%5Csqrt%7B6%5E2%20%2B%2010%5E2%7D%5C%5C%20%3D%20%5Csqrt%7B136%7D%20%5C%5C%3D%202%5Csqrt34%7D)
