Question

simplify
x^3 times x^-5

Answer 1

Add the exponents.

Answer 2

= x^3 + (-5) = x^-2 = 1/x^2

Answer 3

\[\Huge a^ b \times a^c = a^{b+c}\]

Answer 4

3x^2 * -5x^-4

Answer 5

@maryamali , try posting the question on left pane! :)

Answer 6

in*

Answer 7

3*-5*x^2 + (-4) = -15x^-2 = -15/x^2

Answer 8

hey harikat, i don't know if i'm wrong or you are, is it meant to be differentiated?

Answer 9

No, we have to multiply.
\[\large (3 * -5) (x^2 * -x^4)\to (-15)(x^{-2})\to -\frac{15}{x^2}\]

Answer 10

why differentiated????

Answer 11

don't you have to add the powers? so it would be -2?

Answer 12

the solution is as I and saifoo have shown

Answer 13

ok thanku
