Question

Evaluate b2c-1 for b = -4 and c = 2.

Answer 1

-17

Answer 2

-4 x 2 x 2 - 1

Answer 3

just plug in the values.

Answer 4

I believe you meant for the numbers to be exponents
if so,
(-4)^2 * (2)^-1

Answer 5

so b^2(c)-1
=(-4)^2(2)-1
=16(2)-1
=32-1
=31

Answer 6

If it was exponents. If not, it'd be -17

Answer 7

yeah. they weren't clear on that

Answer 8

usually when the numbers are spaced like that, it would suggest exponents
(-4)^2 * (2)^-1 would not be 31 though

Answer 9

These are the answers, -8

4

8

32

and sorry the numbers are supposed to be exponents.

Answer 10

is "c" in the exponents?

Answer 11

I think its 32 though.

Answer 12

alright
(-4)^2 * (2)^-1
expanded becomes (-4)*(-4)*(1/2) = ? can you do that

Answer 13

no, c=2

Answer 14

@jigglypuff314 8

Answer 15

correct :)

Answer 16

do you mean that c is to the power of -1? or just minus 1?

Answer 17

So it equals 8?

Answer 18

if c is to the power of -1
then yes, 8

Answer 19

is how it looks dg, thank you jigglypuff
