Use factoring to write an expression that is equivalent to 25b^16-64c^2

We can write this as the difference of squares:
(5b⁸+8c)(5b⁸-8c)

To write as the difference of squares, take the square root of each term first:
√25b¹⁶ = 5b⁸; √64c² = 8c

Now we write this as a sum in one binomial and a difference in the other:
(5b⁸+8c)(5b⁸-8c)

Can someone plzzz hekppp meeee

erastova [34]

Answer:

Use this formula for these kinda things.

Step-by-step explanation:

Remember The z is the hypathonous, it means the biggest side.

${a}^{2} + {b}^{2} = {c}^{2}$

where Z is going to be C

put this all together

${7}^{2} + {18}^{2} = {z}^{2}$

put it into calculator, means 373=

${z}^{2}$

therfore take the square root, it will be

$z = \sqrt{373}$

which it will be 19.31
