Which grade would you get on a math test?

For everyone saying number 2 is wrong, it isn't. Squaring a negative number multiplies it by itself, meaning two minus signs that cancel; e.g. (−3)² = 3² = 9. The rule is to cancel pairs of minus signs.

This test needs to be rewritten. Answer #2 is wrong. It is 9.8, NOT -9.8. Answer #5 is an inaccurate approximation. (75.4)² is 5,685.16, not 5,684. The square root of 5,684 is approximately 75.39230729.

Good brain exerciser !!!

Number 2 should be 9.8 not -9.8 Mostly just simple math. Fairly simple. Thanks for answers.

Thanks for the answers! Good quiz!

The answer for #2 should be 9.8, not -9.8.

Karin Johansson, And they won't. Quizzclub continues to publish incorrect information no matter how many complain. They simply don't care! They are lazy and unprofessional.

#2 is incorrect. The sign is wrong

-5×-9.8=49
