Why can’t we take the square root of a negative number? provide example.

Zero has one square root which is 0. Negative numbers don't have real square roots since a square is either positive or 0.

because its irrational if you have a negative sqaure root you would have to turn it positive by turning it to a fraction or if it's already in a fraction the you have to switch the side it's on and you could change the negative if it's a whole number that you should make it a fraction by putting a 1 under it

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
