Answer 1

49.0 - 1.5 = 4.75 You would change 49 into a decimal by adding the point zero. After you convert the whole number into a decimal you would then subtract.

Answer 2

I'm confused...

Answer 3

Because it's an exponent...

Answer 4

Im so sorry, I misread it. Give me a sec to work it out

Answer 5

It's no problem ...thank you

Answer 6

All you need to do is multiply -1.5 by 49. To make it easier you would make 49, 49.0 then multiply. The answer should come out to be -73.5

Equation: 49.0 x -1.5 = -73.5

Answer 7

That's the same answer I chose but it was incorrect... I'm thinking maybe we have to square the 49 first

Answer 10

I'd appreciate it... thank you. Hopefully you have a goo day as well.

Answer 11

\(\Large 49^{-1.5} = [(7)^2 ]^{-3/2} \)

got this part ?

Answer 12

I understand everything except for where the -3/2 came from... is that the fraction form of -1.5

Answer 13

yes, thats correct, -1.5 = -3/2
then,
the exponents gets multiplied ,

2*(-3/2) = -3
so, its just 7^-3 = 1/7^3 = 1/343

Answer 14

Thank you... I understand
