Some algebra help, please?

Question

(-60)(-1/2^19)=?

I'm really unsure of what to do here. Can anyone point me in the right direction?

Answer 1

calculator.

-0.5 raised to the 19th power. use the y^x button on the scientific and the ^ button on the graphing. then multiply by -60.

Answer 2

(-60)[(-1/2)(-1/2)(-1/2)(-1/2)(-1/2)(-1/...

=(-60)(-1/524288)

=60/524288

=30/262144

=15/131072

you see, (-1/2^19) means you multiply -1/2 nineteen times. so the answer is -1/524288. and the parentheses is another way to say multiplication so it's like -60 x -1/524288. Then, you cancel the negative signs because we all know that negative multiplied by a negative is a positive. then all that's left is to multiply and simplify.

Answer 3

(-60)(-1/2^19)= -60*(-1/2*-1/2*-1/2... for 19 times, right?)

(-60)(-1/5242880)=

15/131072

Get a calculator and do the math.

Answer 4

-60*-(1/2^19)

-60*-1/524288

-s cancel

60/524288

0.00011444
