 Question from Samiya: i have been struggling with the laws of exponents so I'm having trouble with this question. the question is to write (b*exponent2*c)(b*exponent5*c*exponent4*)

Hi Samiya,

You have

$\left(b^2 \times c\right) \times \left(b^5 \times c^4\right)$

Since multiplication is commutative this can be rewritten

$b^2 \times b^5 \times c \times c^{4}$

or

$b^2 \times b^5 \times c^1 \times c^{4}.$

Using the Laws of Exponents this is

$b^{2+5} \times c^{1+4} = b^7 \times c^5 = b^7 c^5$

I hope this helps,
penny
