Question

5 questions please HELP!!!!!!!!!!!!!

Answer 1

can you help me

Answer 2

possibly....what are you having trouble with ?

Answer 3

ok let me type it for you

Answer 4

Evaluate (-7) 2 (the 2 has to be at top of the 7 FYI)

Answer 5

I do not understand your question...is it just (-7) * 2 or is it -7/2 ??

Answer 6

or -7^2 ??

Answer 7

no its soppose to be like this : (-7) 2 but the two has to be at the top of the 7 but I don't know how to do that

Answer 8

you mean -7 squared ??

Answer 9

yes!!

Answer 10

ok.... -7 ^2 = -7 * -7 = 49

or if you had -7^3...it would be -7 * -7 * -7 = 49 * -7 = -343

but be sure and keep track of your signs...neg * neg = pos....neg * pos = neg.

Answer 11

does that help ?

Answer 12

so its -49?

Answer 13

not quite.....-7^2 = -7 * -7 = 49.....neg * neg = pos....so you answer is 49, not -49
