Question

2(Square root 80/5 -5) = ??

Please help and show work! =^-^=

Answer 1

To solve the expression 2(√(80/5) - 5), we simplify the square root first, then subtract 5, and finally multiply by 2, which results in the solution -2.

Step-by-step explanation:

To solve the expression 2(√(80/5) - 5), let's first simplify the square root and the division inside it.

We have √(80/5) = √16 = 4, since 80 divided by 5 is 16, and the square root of 16 is 4.

Next, we subtract 5 from 4: 4 - 5 = -1.

Finally, we multiply the result by 2: 2 * (-1) = -2.

Therefore, the solution to the expression 2(√(80/5) - 5) is -2.

Answer 2

2(squareroot 80/5 - 5)

to write -5/1 as a fraction with a Common Denominator, multiply by 5/5


2 squareroot 80/5 + - 5/1 5/5

write each expressions with a common denominator of 5, by multiplying each by an appropriate factor of 1

Combine:
2 squareroot 80/5 + - 5/1 . 5/5


Multiply by - 5 by 5 to get - 25
2 squareroot 80 - 25/5


Subtract 25 from 80 to get 11
2 squareroot 11


The result can be shown in both exact and decimal forms:
2 squareroot 11

decimal form:
6.63324958....


Hope this helps!!!!
