Problem

Correct Answer

Your Answer

( ^-3w^-3 )( 2w )

Solution

( ^-3w^-3 )( 2w )	=	-3 • w^-3 • 2 • w¹
	=	( -3 • 2 )( w^-3 • w¹ )
	=	-6 • w^{-3 + 1}
	=	^-6w^-2

Problem

Correct Answer

Your Answer

( 3y )( 6y^-4 )

Solution

( 3y )( 6y^-4 )	=	3 • y¹ • 6 • y^-4
	=	( 3 • 6 )( y¹ • y^-4 )
	=	18 • y^{1 + -4}
	=	18y^-3

Complexity=5, Mode=exponent

Simplify the following. Expand to the form ab^c, where a & c are numeric and b is a variable, such as 3x². Use ^ for exponent, like 3x^2.

Problem

Correct Answer

Your Answer

( 10h^-3 )( -h⁵ )

Solution

( 10h^-3 )( -h⁵ )	=	10 • h^-3 • -1 • h⁵
	=	( 10 • -1 )( h^-3 • h⁵ )
	=	-10 • h^{-3 + 5}
	=	^-10h²
