Thank you. Somehow you are the only person on the internet that actually explained this question correctly.

You missed out the fact that it should be -3^4 at the end giving -90720 NOT 90720!!!

Thanks, even though I’m sitting British exams, not American ones

[@kingbao9733]

Can you explain what the question is asking? What does it mean by constant in a term. I’ve searched it up but it only comes up with a basic algebra definition.

[@tessaparis6413]

a constant is when the number isnt multiplied by a variable. For example, in x^2 + x + 3, the constant is 3.

This was so helpful
Thankyouu so much !

[@daniloloma7367]

I dont understand why the (1/x)^r becomes x^-r? How did you come up with that:(:(

[@robertbrett3350]

exponential properties : 1/x = x^(-1) . so X ^ (-r) is the same thing as (1/x)^r or 1^r / X^r = 1/x^r
