Multiply and simplify:

b3 • b • b4 • b2

b9

b24

4b10

b10

b^10

by property of exponents we have the relationship;

a^b*a^c=a^b+c

So we have:

b^3*b*b^4*b^2=b^3+1+4+2=b^10

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
