Question

Help needed please im stuck

Answer 1

a) b^3

b) x^3

Explanation:

It can be helpful to think of the exponent as specifying the number of times the base is a factor in the product. Of course, common factors in the numerator and denominator cancel.

a)

`(b^7)/(b^4)=(b\cdot b\cdot b\cdot b\cdot b\cdot b\cdot b)/(b\cdot b\cdot b\cdot b)=b\cdot b\cdot b=b^(7-4)=\boxed{b^3}`

__

b)

`(x\cdot x^5)/(x^2\cdot x)=(x\cdot x\cdot x\cdot x\cdot x\cdot x)/(x\cdot x\cdot x)=x\cdot x\cdot x=x^(6-3)=\boxed{x^3}`
