Did I do it right?

x= 2
y= -4

5x^2y
=5*4*(-4)
=-80

You're a bear, you can't calculate.
Silly bear

Looks right to me. I see you accounted for the negative sign, I always make that mistake.

>> No.1745833

Yeah, but that's a shitty way to write it.

>> No.1745861

Wrong, it's 5X to the 2y power, or perhaps 5X to the second power, that quantity multiplied by Y. (Fucking parenthesis, how do they work?)
So either 10 to the -8 power, or 10 to the -4 power, quantity multiplied by 2.
So either .000001, or .02
Lrn2 parenthesis

ITT : Fucking retards

there is no paranthesis, therefore
5*x^2*y -> 5 MULTIPLIED BY X SQUARED MULTIPLIED BY Y

>> No.1746019

but he said
5x^2y
that means x^2, not 2y
